A few problems - there is only a tiny space heater in the unit which doesn't heat the entire place. Heat can be turned on by the host, but if they are not home when you are, this can be problematic. Also, there are large barking dogs upstairs. Oh, and there was half a roll of toilet paper, so we had to resort to paper towels until we were able to get more.
Overall, the place was clean and in a good area for the price. Close to Golden Gate Park and the museums, access to public transportation, a quiet neighborhood, good restaurants in the area, and attractions are within a 20-30 minute driving distance.
