The apartment was lovely as "described" by the pictures. The location was fine for us as we walk all over the places, Union Square, Mission District, Castro, and SF MoMA.
The apartment was spacious except the bathroom, especially the sink. It's not easy doing the daily routine without splashing the water a little bit.
San Francisco isn't what it used to be. The city seemed dirtier and has a lot more homeless people. Know the neighborhoods when you plan your trip.
