Serena's place on the hill is a lovely retreat from the hullabaloo of the downtown area of SF. I felt very safe, also coming home late at night. Wi-fi was very good in all parts of the apartment. The bathroom was squeeky clean and the water pressure was superb - frequent travelers know the importance of this! :-) Good matress in the bedroom and spacious wardrobe/drawers. Shops and public transportation are in walking distance and also some pretty good restaurants and bars (with live music) are located just a few minutes up the street. Recommendation: If you can, try and do the SF Cityguides walking tour of "Portrero Hill" - super informative and it starts just at the Nabe, a few blocks further up. Communication with Serena was always super quick and I felt very welcome. Top ratings from me!
