Venue: The place is relatively spacious for this type of business. There is a bar and even a billiard table, along with a generous outdoor area facing the alley, equipped with tables, benches, and stools. On the upper floor are the rooms for other services, accessible via a nice wooden staircase near the entrance.
The rooms vary in type. Most have walls that do not reach the ceiling. Some are equipped with a bed, others with a sofa or armchair—or both. Instead of the typical low sinks (pardon the crude phrasing, but it conveys the idea), there are standard slightly higher sinks. For certain services, a small two-step wooden platform is provided to make the procedure less awkward—though it’s best to avoid if intoxicated.
The venue itself is not bad; the structure is interesting and potentially pleasant. Unfortunately, most of the space is unused. While everything is clean, the upper floor dedicated to services and the veranda where the girls wait for clients are the areas primarily in use.

Girls: There are around fifteen girls in total, of which two or three are quite attractive, a handful are around average, and the rest represent a mix of all categories, for better or worse. Exceptions aside, the girls’ strengths are oral service and general attitude. (Based on my personal experiences at Duangporn Haven, the service is excellent, and there are some very friendly and skilled girls—but of course, I haven’t tried them all^^).

Prezzi: The rate for a BJ service is 800 Baht for 30 minutes. Full Service is also available, but there isn’t a fixed service menu. Prices generally start around 1,200 Baht and can vary considerably depending on several factors: the girl chosen, the type of room, the time, how attractive she finds you and whether she is in the mood or not (in this case, if she chooses you as a client first, it’s easier), whether it’s arranged in advance or simply a quick upgrade of the ongoing BJ, and so on.

Opening Hours: Every day from 10:00 to 01:00 .

Restaurant/Bar: Technically, it’s a bar with rooms on the upper floor. It was originally designed this way, although it has lost its initial concept over time. However, nothing prevents you from stopping by for a beer in the company of the girls before or after the service. Drink prices are in line with other bars in the area.

Notes: Duangporn Haven carries on the legacy of the famous Som’s Haven from Soi 14, which closed years ago and moved to this larger location on a small side street off Soi 16 (Rachadaphisek Road), about 100 meters from Asok BTS—practically the same distance as Soi Cowboy but on the opposite side of Sukhumvit, where the even-numbered sois are located (link to the exact location on Maps is below).
The girls’ lineup is not exceptional in terms of appearance, but with a bit of luck, you might find one of the two or three younger and attractive girls available. The advice is not to focus solely on looks, as even the less attractive or older girls can provide very good satisfaction for the simple BJ service.
Otherwise, the venue is more of a “quick stop” or better described as a “get in, get out” type.

In short, although this is technically also a bar where you can have a drink in the company of the girls and offer them Lady Drinks, the bar is practically minimal and mostly unused. There is no obligation to buy drinks, and most clients choose a girl before entering and go directly upstairs via the staircase. For this reason, it is generally considered just a simple pump station, where Full Service is occasionally offered at rates below the area’s average.
Personally, I can only speak positively of it. Provided you choose the right girl, it’s an excellent low-cost option to spend half an hour relaxing while enjoying great service in a quiet, reasonably decent environment, even if it’s somewhat underutilized.
