David's place was great value. We were six altogether so it was a bit tight, especially with only one washroom, but all in all it was great for what we paid. It is located in Little Italy which was excellent, and walking distance from the Embarcadero. Large parties be warned, the real bed as well as the pullout couch are only double-sized.
Only complaints we had were that one of the two air mattresses absolutely would not stay inflated though the night, which ended in us sleeping 3 to the double bed. We tried to contact the host but didn't get a response. Also, the sink was broken (but useable), and the shower drain was very clogged.
Jason (David's property manager) was very nice, and provided us with breakfast groceries and fruit. Overall, we had a great time staying here and would recommend it for parties of four, or larger parties that are QUITE comfortable with one another. Great vacation!
