I was with two lbs doing a threesome at Playhause Thonglor in May.
This hotel is interesting. The room is tiny especially the bathroom which has only a small shower cubicle and only big enough for one person use at a time.
However, the bed is comfortable and the fabric is of good quality, the water is hot and pressure is fine. The rooms decor is classy and funny, so my guests easily went into mood for the fun.
It is a lb friendly hotel modified from a small building. The staff is helpful. Rate is closed to 2k per night. It is just close to thonglor and therefore easy for good restaurants, bars and clubs.
