Excellent stay. This not a traditional bed & breakfast but rather a small apartment in visitor's own use. A very good kitchen and a bathroom with shower and bath. Very recommendable and worth the money, at leastbif a 20-min. bus ride to SFO center is okay with you. Buses ride often and are cheap with 3-day pass and easy to use.
The house is in a good, lively neighborhood yet close to small restaurants, pubs and small shops. There is a construction site across the street and they start 7 sharp. Otherwise peaceful, the street is a calm one.
Our host Matthew was flexible, ready to help and easy-going. Arriving a bit early, there were no sheets yet but we found towels for shower. The apartment was clean and ready for us. Matthew came later in the afternoon and brought sheets, soaps and stuff, and asked if we needed something. When leaving, we had a little problem with luggage as our flight was leaving only after 9 PM but Matthew found a solution for that too.
One thing to improve; the double bed is too short. I'm not longer than 180 cm but my feet hang in the air. Also, we felt that the bed was too narrow for two adults to sleep comfortably. One of us had to sleep in the extra bed. This problem fixed, the place will be near to perfect.
