The location and unit itself was awesome. Not in the heart of SF but close enough to see all the sights and avoid major traffic. The unit was extremely clean and our hosts were very communicative. The only major flaw was our sleeping arrangement. The rooms appeared to be identical, but one of the two mattresses (in the far bedroom, no connected bathroom) was extremely uncomfortable especially for two people to sleep on. Only on the day of our checkout did we realize the mattress in the first room with the connected bathroom was newer, not a spring mattress, and far more comfortable. Everything else was great, but since we were only there to shower and eat it was a bit of a downer.
