My partner and I stayed for three nights in the private room and we absolutely adored the place! The room was big and spacious with large windows that allow much light in with blackout curtains for privacy and keeping strong light out, the shower was heated, hangers provided, and a gigantic bed that was comfortable to sleep in! Airconditioning was great and kept us nice and cool in the hot Bangkok weather. A refrigerator and microwave, with cutlery and dishes were available at the common space for our convenience as well.
Service and hospitality was warm, inviting and helpful. Checking in was quite efficient as well. The check in counter was together with a cafe that filled the space with a wonderful coffee aroma but unfortunately we did not get to try the cafe out during our visit to Bangkok.
The location was great too, only a few minutes walk from Saphan Taksin BTS, with various hole-in-the-wall eateries where I had some of the best food on my trip, and a decent bar down the street :)
Overall, we enjoyed our stay very much and would recommend it as one of the best places to stay if you want to be in the Silom/Bang Rak area. Bravo!
