Park Plaza Bangkok Soi 18 — Rooftop Pool at the Heart of EM District, BTS in 5 Minutes
If you want to stay on prime Sukhumvit, within easy walking distance of two rail stations and the EM District's trio of malls, without paying five-star prices, Park Plaza Bangkok Soi 18 is a name worth shortlisting. This 4-star Radisson property sits on the quiet middle section of Soi 18 — a five-minute walk from BTS Asok and MRT Sukhumvit, and strolling distance from Emporium, EmQuartier and EmSphere. Opened in 2011 with 125 rooms across 11 floors, its calling card is the rooftop Sway Pool Bar — a skyline-view pool that guests mention more than anything else in their reviews. Rates start from around ฿1,900 per night, with a score of 8.6 from 2,643 reviews on Booking.com. The Japanese dining strip along Sukhumvit 24–39 and the green lawns of Benjasiri Park are both within easy reach, making this a well-rounded base for both leisure and business stays.
Park Plaza Bangkok Soi 18 opened in 2011 on a short connecting soi between Sukhumvit Road and the Khlong Toei neighbourhood — what guests consistently call "quiet enough to sleep, close enough to walk everywhere". Soi 18 slots neatly between BTS Asok (Soi 21) and BTS Phrom Phong (Soi 30/1), with the hotel's 5-minute walk to BTS Asok and MRT Sukhumvit being one of the most-cited reasons for return visits. Terminal 21's playful travel-themed floors are a short stroll away, which is handy for grabbing a meal or supplies without firing up Grab.
The 125 rooms are dressed in warm chocolate-brown neutrals and wood tones — a mid-2010s aesthetic that still holds up reasonably well. Reviewers consistently note that rooms feel more spacious than expected at this price point, complete with a desk, minibar, in-room safe, DVD player and complimentary Wi-Fi. Higher-floor city-view rooms make the most of the building's position, while some lower floors pick up road noise on busy evenings. The Executive tier adds lounge access and a more elevated floor perspective.
"Room was larger than I expected, very clean. Staff at front desk were genuinely helpful. Walked to BTS Asok in under five minutes — excellent value for a 4-star in this location."
The hotel's standout amenity is the Sway Rooftop Pool Bar — an open-air pool on the upper floors with a bar serving drinks and snacks against a Bangkok panorama. It draws the loudest praise in guest reviews, particularly for the atmosphere during early morning laps and evening sundowners. There's also a spa and massage rooms for unwinding after a day of mall-hopping, and a fitness centre that covers the essentials. The rooftop becomes a social hub in the cooler months (November to February), when the heat eases and the views are at their clearest.
Mezza Restaurant handles breakfast, lunch and dinner with a broad menu spanning Thai, Italian, European, American and Asian dishes. Breakfast reviews are mixed — the spread is considered adequate for the price, but freshness and variety can be uneven depending on the day. A highlight for many guests is Daryaganj, the hotel's Indian restaurant, which earns specific praise from South Asian travellers for its butter chicken and biryani. Having two distinct restaurants under one roof gives more dining options than most competitors at this rate.
Honesty matters here: the most consistent complaint across Booking.com and TripAdvisor centres on maintenance. The hotel is over a decade old and some rooms show it — shower temperature controls that are fiddly, occasional shower-head drips, and room lighting that several guests describe as too dim for reading or working. Wi-Fi signal drops in rooms farther from access points on certain floors. These are real downsides that a renovation would fix, but they haven't happened yet. Staff scores — 9.3 for service, 9.1 for location — remain the hotel's brightest points.
For shoppers and food explorers, this location is hard to beat: EmQuartier is roughly a 10-minute walk, Emporium is right next door to it, and EmSphere (the newest addition to the EM District, opened late 2023) is just across the street. Benjasiri Park — popular with morning joggers and evening picnickers — is a quick 8-minute stroll. Rates typically run from around ฿1,900–2,800 per night depending on room type and season, with occasional dips below that range during slow periods.
