I have had offers from 2 hotels. In Silom, forget about it. There no are hotels in my price range, with pool.
I got 2 offers writing to the hotel, both stating being gf. The first is Citichic, who has prices asking around 1800 /night, the second is Galeria 12 at slightly higher 1987. Which would have your preference? There is also a Galeria 10, older, bu its a bit cheaper. Will be mostly location, to make a choice. I prefer more restaurants besise, then into your face nightlife, as long as the massage parloirs are not too far.
Oh yes prices are included everything, Galleria throws in a dinner coupon of 400 bht, which I will not use anyway. They ask for early check in, half price if room is still available.
