I highly recommend Rob's place. We had a tricky situation with our flight date and times and he helped us out and saved us a lot of trouble. It's absolutely freezing in SF right now but Rob's bedrooms have great heating so we were toasty warm. The beds and pillows are amazing! The walls are well insulated so we couldn't hear the other guests. The whole house is immaculately clean. You can get a bus direct to downtown from a block away. We bought a weekly Muni pass so getting around was super easy. There are a ton of cheap yummy restaurants on the block. We really loved the Mission area. I hope to stay here again next time.
