This has been by far one of the best stays I've stayed at! My friend and I felt very welcomed by Mary and her family. She was really kind and accommodated us a lot during our stay. We visited during Christmas, and she prepared lots of food for the guests (even though we had other plans that day). If you want to stay near downtown or travel in SF, this is a great place to stay since it's very close to bus/bart/metro stations, Union Square, Chinatown, and etc.
