Safe and secure building in a location convenient to walk to many areas of the city from SomA to Russian Hill. The place felt like a cozy home and not a bare bones short-term rental set up. Everything from the host side was handles timely and professionally. Security guards at the front desk are all professional and polite. Other building guests are friendly as well. Noise is a big issue for me when being somewhere and this place was incredibly quiet. 5 stars.
