This is a reasonable base for exploring San Fransisco albeit some way out. The building is on a very noisy corner and traffic will wake you in the morning.
The owners do leave some clothes on the floor in their bedroom and other effects around. The bedding on the two "proper" beds is low quality. So it has the feel of a post-grad student flat. OK if you like that sort of thing.
We were unlucky with the fire alarm going off twice at night with several fire trucks arriving both times (1am and 3am). Plus the battery ran out on the door key pad so we were locked out with kids on hot day.
it is what it is. 3*
