Pros: The host is very nice and responsive. The location of the house is okay It's 10 ~ 15 min walk from the Balboa Park Bart station. The neighbourhood is quiet and the it's close to a Walgreens; I'd recommend sandwich at Roxie Food Center and Beijing restaurant serves the best Chinese food I've had in SF so far. The house is quiet and it has a lovely garden on the front.
Cons: The room is down in a "basement", it's quite cold and the celling is very low. The bathroom on the same floor is not clean. It makes you think of the restroom at a Bart station -- I never used it. The bathroom upstairs is much better. The kitchen and the fridge have a stink. And there is no light in the kitchen. The window of the room is blocked by the wall of the house next door so basically you get no window.
