First of all, the location is fantastic: you're right on Divisadero, with all its restaurants and shops, a 15 minute walk away from Hayes and Height, and a few blocks away from Alamo Square, which might be one of the nicest places in the city. The neighborhood is safe enough (as any place in SF goes), and the added metal gate made it feel extra secure.
The apartment is in a building behind the main house, which makes it amazingly quiet for the area. Sound does carry extremely well from the studio apartment downstairs, which was unoccupied for most of our stay.
Apartment itself was not exactly new and shiny (walls could use a coat of paint, the curtains are old and dusty, the bed creaks very loudly if you as much as look at it), but it was well-stocked and reasonably clean, and the wi-fi was very fast. Has more of a feeling of a college dorm than the upscale living you would expect for that price in most other cities, but hey, welcome to San Francisco.
