I will definitely recommend this place for a San Francisco stay.
We got a very good attention from the check-in desk, and they give us lot of address that were nice to see.
About the room: it was very nice and clean, and the 7th floor is very quiet room :) !
Bed is comfortable, with all included (towel and bath products).
The location is amazing, down-town, just 2 minutes walk from Union square .
