This place is REALLY nice! Book it!
As others have mentioned its small and in a sketchy looking neighborhood, but there really were no issues. Neighbors that we saw were nice. No evidence of car break-ins (just don't leave stuff in your car when you are visiting the Bay Area). And it was quiet.
The place itself was really clean, brand new and modern. Everything worked like it should have, and it was in general a very comfortable place to stay in. Unlike any in-law unit in the bay, it wasn't dark or damp or any of those things. Private entrance, lots of natural light, warm (heater) and cozy :)
Dave and his manager/partner were really responsive too. Even called us when we couldn't figure something out.
Great stay! Don't be put off by the industrial neighborhood and book it!
