PASSA Hotel Bangkok — New Silom Boutique Hotel, a 3-Minute Walk from BNH Hospital
If your stay in Bangkok revolves around BNH Hospital — whether for a medical appointment, accompanying a patient, or just needing a well-located Silom base — PASSA Hotel Bangkok sits closer to BNH than any other quality hotel in the neighbourhood. The hotel opened in 2021 at 63 Soi Saladaeng 2, roughly 215 metres from BNH Hospital on Convent Road — about a 3-minute walk, with no major road to cross. It is a 36-room boutique property with hand-painted murals unique to each floor, a rooftop infinity pool, a city-view bar, and a guest score of 8.9/10 from 718 verified Booking.com reviews. BTS Sala Daeng is about 8–10 minutes on foot; MRT Si Lom is about 6 minutes. Rates start from around THB 2,900 per night for a Superior Room.
PASSA Hotel opened its doors in 2021 and quickly built a loyal following among travellers who have learned the hard way that proximity to a hospital matters when schedules hinge on appointment times. The property is a six-floor boutique with 36 rooms, positioned at the end of Soi Saladaeng 2 — a quiet, low-traffic lane that connects to Saladaeng Road. Walk out the front door, follow the lane towards Convent Road, and you are standing at the entrance to BNH Hospital in roughly three minutes, with no traffic lights or major crossings to navigate. For Bangkok, where a Grab ride at rush hour from a "nearby" hotel can take 20 minutes, that matters enormously.
The design is the first thing guests notice. Every floor carries its own hand-painted mural — artwork commissioned by the hotel and executed on-site, each piece weaving together Chinese, Indian, Western and Thai visual traditions into something unmistakably original. The floors do not match, and that is exactly the point. Step out of the lift on the third floor and you are somewhere different from the second. It gives a 36-room hotel the feel of a gallery that also happens to serve a very good breakfast. Rooms run from Superior at 23 sqm (King or Twin beds) to Deluxe at 30 sqm (King or Twin, adding a full bathtub). All are equipped with a 50-inch Smart TV, Nespresso machine, in-room safe, rainfall shower and free high-speed Wi-Fi.
"We were at BNH every single morning for a week. Being able to walk over in three minutes, have a proper breakfast, and walk back to the hotel in between appointments made an exhausting situation genuinely manageable. The room was spotless and the bed was excellent."
The rooftop is the hotel's leisure centrepiece. A compact infinity-edge pool sits at the top of the building, framing a low-rise Bangkok skyline that few newer hotels in Silom can match for intimacy. It is a pool for soaking and unwinding, not for lap sessions, but the views at dusk — when the office towers in Sathorn light up — draw guests back evening after evening according to the reviews. Adjacent to the pool is a rooftop bar with a themed speakeasy aesthetic; it is consistently described as one of the more atmospheric options in the Silom area at this price level. There is also a gym for those who want it, alongside a café and restaurant on the lower floors serving à la carte breakfast from 07:00 to 10:00 daily. Several reviewers specifically praise the freshness of the food — made to order rather than warmed in a bain-marie — as a meaningful differentiator.
Transport options out of the hotel are solid. MRT Si Lom station is approximately 510 metres away — about six minutes at a normal walking pace — making it the more convenient option for heading north towards Hua Lamphong, Sam Yan and Silom MRT junction. BTS Sala Daeng is roughly 810 metres (eight to ten minutes walking), connecting south and north on the Silom Line with easy interchanges to the Sukhumvit Line at Asok or Siam. Lumpini Park — one of Bangkok's best morning-run circuits — is around 15 minutes on foot. The Silom-Patpong area with its dense concentration of street food, restaurants and night market is effectively on the doorstep.
The service quality stands out in the review record. Across Booking.com (score 8.9) and Agoda (score 8.9, over 2,600 reviews), the staff score comes in at 9.4 — the highest category. Guests describe front desk staff who remember names, arrange early check-in when rooms are available, and handle maintenance requests the same day. One reviewer mentioned finding a birthday amenity in the room without having disclosed the occasion, another the hotel replacing a room at no charge after a musty odour was reported. For a 36-room independent boutique, this level of attentiveness is a genuine operational choice, not a marketing claim.
Honest balance: the pool is small — guests who arrive expecting a swimming facility comparable to a large-resort pool will be disappointed, and the reviews are clear about this. A handful of reviews also flag humidity or mustiness in certain rooms (the hotel provides dehumidifiers on request, and staff respond quickly). Superior rooms at 23 sqm feel comfortable for a short stay but may feel tight over a week-long visit; the Deluxe upgrade to 30 sqm with a bathtub is well worth the price difference if budget allows. Evening dining within the hotel is limited; the neighbourhood compensates generously with countless restaurant options within a five-minute walk.
On value: rates start from around THB 2,900 per night for a Superior Room in low season, rising to approximately THB 3,400 for Deluxe and higher still during peak periods and long weekends. Against other 4-star boutique hotels that opened in Silom since 2019, PASSA's combination of proximity to BNH, original design, and consistent service justifies the price for the majority of the guests who review it. The 8.9 score across nearly 3,400 combined reviews on the two main OTAs is not an outlier — it reflects a property that delivers reliably on what it promises.

- 💡If you are managing daily visits to BNH Hospital — the 3-minute walk means no traffic, no Grab cost, no scheduling stress between appointments. Book the Deluxe Room (30 sqm + bathtub) for stays of three nights or more; the extra space makes a meaningful difference over a longer admission.
- 💡If you are sensitive to humidity or room odours — a minority of reviews flag mustiness in certain rooms. The hotel provides dehumidifiers and the front desk has a solid track record of room changes when asked. Raise any issue immediately on arrival.
- 💡If you need a serious swimming pool — the rooftop infinity pool is genuinely beautiful and the view is exceptional, but the surface area is small. For lap training or families with active children, check other properties in the roundup.
