Yes, 2 nights last November.
Really nice rooms (was in an executive room) great location (skytrain and metro right outside), Lumpini Park nearby (although I gather the market has since closed) and the joys of Patpong (I mean shopping obviously) within a couple of minutes walk.
I really enjoyed it. It's primarily a business hotel, and it feels so, but I would make it my first choice location wise (if I didn't stay in different hotels every time!).
