Casa Nithra Bangkok — a rooftop pool in quiet old-town Bangkok, ten minutes from Khaosan Road and a short stroll to the Chao Phraya riverside
Casa Nithra Bangkok is a 4-star boutique hotel at 176 Samsen Road in the Ban Phan Thom neighbourhood of Phra Nakhon — close enough to Khaosan Road that you can walk there in ten minutes, but far enough that you will sleep well. The hotel opened in 2014 with 74 rooms built around a rooftop outdoor swimming pool and Sirin Thai Dining and Bar. Phra Sumen Fort is a five-minute walk away; Santichaiprakan riverside park is slightly further; Phra Athit Pier (Chao Phraya Express Boat) is roughly ten minutes on foot. The hotel holds a score of 8.6 out of 10 from 3,074 verified Booking.com reviews, with particularly strong marks for service (9.5) and cleanliness (9.2). Prices start from approx. THB 2,200 per night for a Superior Room in the low season.
The most useful thing to know about Casa Nithra Bangkok is where it sits on the Khaosan Road spectrum. It is not on the road itself — it is a ten-minute walk north on Samsen Road, in the Ban Phan Thom neighbourhood. That extra distance means you get a genuinely quiet street, a row of old Thai shophouses and garden walls rather than bars and tuk-tuk touts, and a room where you can sleep past midnight. The trade-off is that Khaosan, Rambutri and all the energy of Bang Lamphu are still there when you want them — just not pressed against your window at 2 a.m.
The rooftop outdoor pool is the feature that appears most often in guest reviews. It is not a large pool, and it does not look out over the Chao Phraya River — but it is clean, well-maintained, and consistently described as a welcome place to decompress after a long day around the temples. The hotel opened in 2014 and the design threads Thai decorative motifs through a contemporary frame: carved wood details, locally sourced art on the walls, and warm lighting in the corridors that keeps the property from feeling corporate. The 74 rooms are divided into Superior Twin, Superior Double, Deluxe Double and Suite categories, with the Suite adding a separate bathtub and a slightly wider sitting area.
"About a 10-minute walk from Khao San Road but in a quiet pocket. The breakfast had so many good options — traditional Thai and plenty of western choices. The pool was really nice and the perfect temperature. Staff were all so lovely and helpful." — Booking.com guest review (June 2026)
Service is the strongest card this hotel holds. Booking.com rates the staff at 9.5 out of 10, comfortably above the overall score of 8.6 and above most comparable Bangkok 4-star properties. The front desk team speaks good English, responds quickly to requests, helps with transport arrangements, and — a detail several reviewers single out — provides free coffee, tea, fruit and snacks throughout the day at no extra charge. The Sirin Thai Dining and Bar offers a buffet breakfast (American style, 6:30–10:00 a.m., charged separately at approx. THB 395 per person) that earns consistent praise for variety and freshness.
The area rewards guests who are specifically interested in Bangkok's historic core. Phra Sumen Fort is a five-minute walk — a restored cannon tower built in 1783, now surrounded by the quiet greenery of Santichaiprakan Park, where Bangkok residents sit in the evenings watching the Chao Phraya roll past. Phra Athit Pier (Express Boat stop N13) is roughly ten minutes on foot — from there, the Chao Phraya Express Orange Flag service connects to Wat Arun, Tha Tien (for Wat Pho and a short walk to the Grand Palace), and south to Saphan Taksin, where you connect with the BTS Skytrain. There is no BTS or MRT within walking distance of the hotel itself, and guests who need the Skytrain daily should factor in that ferry journey.
Two things come up in negative reviews with enough regularity to mention honestly. The first is street-construction noise from Samsen Road during the day — work stops before 10 p.m. under city regulations, and most rooms manage the noise reasonably, but guests in rooms facing the street may notice it during the midday hours. The second is air conditioning speed during extreme heat: a handful of reviews from the April–May period (when Bangkok regularly hits 40 degrees Celsius) mention that the units take a while to cool the room down. Neither issue is a dealbreaker — and neither affects the pool, the breakfast, or the staff — but they are worth knowing before you arrive.
For travellers who want a 4-star base in the Rattanakosin old town at a price that gives back some spending money for the temples, markets and river boats — Casa Nithra makes a genuine case. The combination of a rooftop pool, a strong staff score, a varied breakfast and a genuinely quiet street is not something every hotel in this district can offer. A score of 8.6 from over three thousand guests across several years is a fair summary of what the hotel actually delivers.

- 💡If you want a large pool with river views — Casa Nithra's rooftop pool is genuinely good, but it is small and city-facing. Riva Surya Bangkok, in the same neighbourhood, has an outdoor pool overlooking the Chao Phraya and Wat Arun — but at a noticeably higher nightly rate.
- 💡If daytime noise is a concern — a handful of reviews mention construction on Samsen Road during the day. Ask for a higher floor or a room away from the street side at check-in; the hotel's internal soundproofing handles most of it, and works stops by 10 p.m.
- 💡If you need daily BTS or MRT access — this area has no rail connection within walking distance. The nearest BTS (Saphan Taksin) requires a ten-minute walk to the river and a 20-minute ferry. If you plan to commute across Bangkok every day, a Sukhumvit or Silom base will save you significant travel time.
