My wife and I stayed 2 nights. Very clean, comfortable and safe accommodations. Our host was very responsive to our email inquiries ahead of time. We saw little of her, which was fine. She had things to do and so did we and our schedules didn't overlap. Wasn't a B&B in the sense that there was really no breakfast provided. Again, that was fine with us considering the price. The only drawback for some might be its location. High atop Potrero Hill, the view is beautiful, but you certainly wouldn't want to walk up there with luggage (I didn't check the parking situation, but generally it is pretty good in Potrero). We would definitely stay again.
