Great location; cozy space
This is a small, cozy boutique hotel a short walk from Union Square. Staff were friendly and helpful, and the night we were there, they offered complimentary glasses of wine around 5:30 pm-- a nice "apertif", if you will. Our room was a bit on the small side, so this is perhaps not the best pick if you have a ton of luggage and need to be able to open big suitcases and spread their contents out, but for us (two small suitcases + some miscellaneous bags), it wasn't a problem. The space was beautifully decorated, clean, and cozy, and we slept like babies. 
It's a short walk from Union Square, Chinatown, BART (2 or 3 blocks), the cable cars, and there's a quite breakfast place next door that was very convenient in the morning. We would stay here again.
