The only issue we had was the quality of the mattress on the sofa bed. There were springs sticking out and it couldn’t be used. We were able to get a cot that was comfortable but we booked a suite especially for the 3rd person.

The rooms are spacious and quiet, We were on a higher floor. The staff were helpful and friendly. Despite some reviews about the area being on the border of the tenderloin we never felt unsafe. There would be no reason to go left out of the hotel which is towards the tenderloin district. Instead you would go right and its a few minute walk to union square. Convenient location to the cable car , transit and walkable to many main areas and attractions.
