I stayed at Alex's place for two weeks in early November and really enjoyed it!
Alex and Guesthop (the company that helps with management) were extremely responsive and helpful. They even laid out a packet of details about the apartment and area which was a nice touch.
First of all, the location is great. It's across the street from a small park/recreation area and a short walk a small produce shop, coffee shop, restaurants and grocery stores. The area is on the quieter side, but at the same time close to busier areas, which is a nice balance.
There is a 24 bus stop right across the street from Alex's place which is super convenient, and its also pretty close to other main transportation outlets that go into the city like the J Muni and 14 bus on Mission Street. Be sure to check out Billy Goat Hill, and 24th St. in north Noe Valley too!
The place is spacious and was very clean. There were heaters in the living room, bathroom and bedroom to keep things warm. The kitchen was equipped with proper dishes, pots and pans, etc. and a coffee maker too.
Overall I'd recommend Alex's place and will definitely keep in mind for future visits to SF.
