Some pros about the listing: the location is pretty central, and it's easy access to pretty much every nice neighborhood. While the actual apartment is kinda dingy and dark, the street it's on is quite nice on the Duboce side.
Cons (get ready, there are quite a few): the host was very uncommunicative for the duration of the stay. There was an ant problem the first few days in the apartment—luckily there was ant killer already provided—and halfway through the stay, the WiFi went out and stayed out for three weeks. Laundry was promised for the entire stay but was under construction for a good portion. The front gate was jammed and hard to enter for a week or so and even after being provided new keys, and it was overall incredibly hard to get a hold of anyone to help out with the various problems.
There are a few other small complaints (the bedding provided isn't enough for two people sleeping separately in San Francisco, there was no toilet paper or hand soap, etc) and the main intersection on Market might be a safety concern (there was one police issue on the block).
