Location was great, very close to Union Square and to Moscone Center. Rooms were cozy, but really excellent and they had everything you would need. Very comfortable bed, fast wifi, clean room, fluffy towels. The ambiance was very cool. Staff was outstanding, extremely helpful, in particular Rebeka at the front desk. Highly recommended.
