We stayed for three nights. The staff was genuinely friendly and very helpful. It was definitely swanky and fun. However, we thought it was over priced. Our 400 sq ft room may have been that on paper, but with the walls, desk, bench, stool and bed, in practicality, it was a 100 square ft. We stayed there because their website hyped their comfy beds. They were more comfortable then a regular hotel bed, but we've had better for less (LeMeridian in Minneapolis). My wife loved the Bliss bath products. So much so we brought them home. It was nice to be close to SFMOMA, but I think next time we'll go to a hotel closer to the subway and cable cars. Respectively, 4 & 6 blks doesn't sound like much, but after a long day, it'd be nice to get off the MUNI and not walk so far to hotel.
Pros: Comfy Bed, Bliss Bath Products, Friendly
Cons: Small Room, Not many Extras, A bit over $
