I rented this place for a month as temp housing when I moved to San Francisco. The apartment was clean, decently stocked for kitchen wares, had reliable good internet (which he recently upgraded), and a great layout. Since the place is actually nestled inside its own little quaint, charming courtyard away from the street and surround by the other buildings, the days and nights are very quiet and relaxing. The bathroom is extremely roomy and very nice!
The place is extremely convenient to several MUNI bus lines and stores. And the neighborhood has some swank views of San Francisco, so keep your eyes opened and head up :-)
The owners are fabulous and extremely friendly, and more than willing to meet up for dinner and drinks. If you stay here, try and make sure you get the chance to say hi to them in person! They are very friendly, warm, inviting, and can give excellent advice about the city.
The owners also made the renting and check-in process painless and simple.
My only critique is that the mattress and pillows needs to be retired, as the mattress sags a little in the center, and the pillows are a bit flat. I didn't lose sleep, but it could have been a bit more comfortable.
If they were renting this place long term, I'd rent it in a heartbeat - I wish they would :-)
