I found an unexpected oasis of tranquillity - and world-class spa - in the heart of buzzy Bangkok

Thailand’s capital has a lot to offer it’s estimated 30 million annual tourists - incredible food, historic temples, and some of the best shopping you’ll find anywhere, from sprawling markets to chic designer boutiques.

One thing less associated with this city, however, is peace and quiet. The typical Thailand tourist mindset is: burn through some energy in Bangkok, then hop over to an island to recharge. That’s certainly what I did when I first visited almost 20 years ago, but it turns out I was missing a trick. If you know where to go, serenity is absolutely an option without any additional airfare, and I found just that at the Capella Bangkok.

This sleek and intimate hotel has built a reputation for its world-class spa, Auriga Wellness, which has won Thailand's Best Hotel Spa at The World Spa Awards for the last four years and counting - and you can imagine how stiff the competition is in that category.

Of course, the beauty editor in me sees spa breaks as the ultimate way to unwind, but as it turns out, Capella’s ability to draw any big-city jitters out of you begins the second you set foot in the door.

What’s the hotel like?

This sleek spa hotel was built in 2020 and sits within a small cluster of luxury options studding this end of the Chao Phraya River. But unlike its towering neighbour, The Four Seasons, Capella likes to wear its luxury lightly, with a discreet, low-rise facade and 101 rooms total.

Every option, from the most ‘basic’ (obviously, not basic at all) Riverfront King, right up to full-blown family villas, is river-facing with, at the very least, a generously sized balcony. This means everyone gets to enjoy far-reaching views right up and down the famous waterway, and a sense of wide open space that's tricky to come by in this bustling megapolis.

My partner and I arrived at the Capella feeling a little tired after four days of fabulous but full-on wedding celebrations south of the city. Happily, for a pair of weary (ok, fine hungover) travellers, check-in happens not by standing around at a desk, but reclining in your own little corner of the hotel's Living Room area, with a glass of restorative fizz, if you fancy.

Decor here definitely falls into the ‘quiet luxury’ category; glossy, but not blingy. Think ebony wood floors, oatmeal-toned furnishings, and large-scale understated artwork. Lighting is warm and friendly, and seating is chic and squishy.

The bedrooms follow suit, all neutral tones and natural materials - jazzed up by local flowers and edible treats that bring a sense of place. Forget your standard hotel shortbread; give me som sai nam phueng (local 'honey orange') and khanom tan (toddy palm cake) any day.

Our Riverfront Premier King felt almost outrageously spacious for a non-suite option, with a little dressing area stuffed with things to make life seamless while you're staying - a shoe shine kit, complimentary soft drinks in the minibar and a roomy leather bag to take your bits and bobs to the pool.

The nice touches continued as I explored the room. I felt my shoulders drop three inches the second I saw the enormous bathtub with a note advising me to dial for a bubble bath (heaven forbid guests should have to run their own) and huge blinds that obediently unfurl across the floor-to-ceiling windows as you leave, to shut out the blazing Bangkok rays as you explore.

Experiences and facilities

Staying at the Capella feels a bit like being in the home of a very stylish and well-off friend - if your friend happened to employ a team of wonderful people called Culturalists. Think: a personal concierge assigned directly to you, but a WhatsApp away to help you navigate the city, plan excursions, and tell you which street food stall has the best crab omelette.

I stuck with fairly prosaic queries, namely: when does the complimentary guest shuttle boat set off up the river (every 30 minutes) and how early do I have to get up to join the sun salutation yoga session (7 am - but well worth it for a good old stretch in the gardens while the city’s waterway wakes up in front of your eyes).

If you prefer to do your own thing, fitness-wise, there's also a gorgeous outdoor pool for some pre-breakfast laps and a very nicely kitted-out gym.

The baked-in activities don't stop there; the Capella offers daily cooking workshops and family-friendly local arts and crafts. My partner joined traditional Thai mask painting and reported that, despite having at least 30+ years on the other attendees, his finished creation sat at the back of the pile for finesse.

We had more success making traditional Thai Khanom Thom dumplings together the next day, enjoying the soothingly undemanding cheffery of rolling out sweet rice flour dumplings and covering them in sweet shredded coconut.

Come 5 pm, the absolute standout activity is Cin Cin hour, a daily gathering in the ground floor Living Room where guests can enjoy a complimentary local cocktail or fizz and what was rather undersellingly described as snacks (edible works of art).

It’s a lovely, sociable anchor point as day turns to night, but also an example of how, yes, the Capella is a top-end hotel and priced accordingly, but there is no understating how thoughtfully that luxury is given back to you, and how totally taken care of you feel at every point of your day.

How does the spa measure up?

It would be reductive to say Auriga Wellness is the main reason to stay at Capella - but this multi-award-winning spa is absolutely a draw. Put it this way: Forbes Travel Guide does not award five-star spa distinctions to just anyone.

As a spa expert (read: spoilt beauty editor) I can be pretty hard-to-please (read: jaded) when it comes to the offerings in hotels, but this was truly next level. Sleek marble decor, low lighting and a clearly very judicious booking system give a feeling of total privacy from the second I entered reception and began sipping lemongrass tea.

The thermal bathing area, which I had all to myself during my visit, has a variety of hot, cold, bubbly and steamy bits and bobs, including a rainforest shower with realistic yet strangely calming tropical bird noises.

Next, I was summoned to my treatment, via the changing room stuffed with Aesop products and - I think this says it all - a class of disposable underwear I didn’t think possible to achieve.

I tried the hotel’s signature New Moon massage, 90 minutes of much-needed deep muscle work incorporating a gua sha on my back and legs and some gentle stretching out. This wasn’t a ‘falling asleep’ treatment so much as an ‘emerge energised and raring to go’ one, which is a good thing because I had a dinner reservation not to be missed.

What food and drink is on offer?

Getting stuck into Bangkok’s thrilling food scene is the hands-down highlight of any visit - or it is for me anyway - and you’d be missing a trick by playing it safe. But say, hypothetically speaking, you were someone who wanted to eat in your hotel morning, noon and night, you could very (very) happily do so at Capella.

Walking into breakfast, my boyfriend got the same look in his eye as my three-year-old son does when I accidentally let him see a wall of pick n mix - the charcuterie! The cheese! The cute little pots of healthier things we ignored!

Not to mention, the most intricate patisserie table I’ve seen outside Paris, and several à la carte menus to cater for Eastern and Western sensibilities (I went for a little basket of dim sum one morning because, why not?)

For a special Italian-influenced lunch or dinner, the tip-top restarant here is the two Michelin-starred Côte by Mauro Colagreco. Or, do as we did and visit Phra Nakhon for Southern Thai specialities on the terrace.

Among the flavour bombs being knocked out by head chef Kannika Jitsangworn, memorable highlights included curry crab with vermicelli noodles, crispy pork and a reassuringly fiery som ta salad.

It's always a good sign when you can tell your fellow diners are, not just hotel guests, but city residents enjoying a special meal - and the spectacle of the river at night, with sophisticated dinner cruises and noisy party boats chugging along in tandem, made it feel like dinner and show.

After a nightcap, we were pointed towards the hotel's tiny, jewel-toned cocktail bar, Stella. Dripping with Art Deco furnishings, just the right side of OTT with pleasingly old-school live piano performance, the gear-change from the Capella’s minimal and tranquil aesthetic felt thrilling - like stepping into a jewellery box.

There’s a bar snack menu to keep you going, and the expert staff can guide you through the cocktail list, which makes use of local spirits and teas. Although you'd be remiss not to try the smoky, fragrant, unlike-anything-I’ve-tasted-before Siam 5.0, with Nikka whisky, fermented Thai honey, jasmine and cognac.

Hotel bars can do a decent trade on being simply the most convenient option, but much like Phra Nakhon restaurant, Stella has an identity of its own, and feels like somewhere you would visit regardless of guest status. Although, luckily for us, we could enjoy world-class mixology in a memorable environment a mere three-and-a-half-minute roll away from bed. Is there anything more relaxing than that?
