This is a nice studio in a great location. My daughter and I stayed here for the weekend to run the Golden Gate half-marathon.
Pro's: Location, location, location! 3 blocks (downhill) to the water / wharf area. We didn't use the car once, though we enjoy walking. Still, nothing we wanted to see was much more than a mile in either direction. The host was very responsive. The kitchen is small, but adequately equipped if you want to stay in and cook. The bathroom (shower) is small but adeqaute. My daughter said the bed was plenty comfortable, and the couch wasn't too bad as a second bed.
Cons: 3 blocks (uphill) from the water! If it is your first visit to SF, the steepness of the hills will be surprising. Still, not so bad. The room is a Studio - and small. Not congested or claustrophobic, but compact. It didn't matter to us, but if you had more than 3 people visiting in the room, it would have been really tight.
Overall, a great stay. I'd certainly stay there if I find my way to SF again.
