I had a great stay at Kathy's. The room is very well located near the buses and the metro allowing to go to Castro or Dowtown in less than 20 mn (30 if you walk and then take the metro). The room is well equipped, spacious, it has a portable heater if you are a little cold and the bed is comfortable. The place is quiet. The bathroom is well equipped and clean. I didn’t use the kitchen but you can use pretty much everything inside so it’s pretty useful.
Finally, Kathy is very nice, friendly and interesting when you talk with her. She also gives advice about nearby transportation and restaurants. Very nice stay, thank you Kathy!
