Location: 5/5
Yes, it's not directly downtown, but for us that was a plus: the house is in a very nice and quiet neighborhood with shops, restaurants and a subway station barely five minutes away. Fifteen-twenty minutes to downtown.

The room: 4.8/5
Everything was great: fresh towels and laundry, a very functional little kitchen, a coffee machine, very good wifi, etc. Perfect privacy, too, since entry is keyless and on the side of the house. The only (very small) downside is the fact that the room is in a kind of semi-basement as the house is located on a hill, which means more humidity and less sunlight.

The host: 5/5
Welllll we didn't get the chance to meet Phil, but the way he set up the room and the information he provided was all we needed.

Value for money: 4.5/5
All in all, everything was great... But yes, it is a bit expensive compared to what you can get for the same price in the rest of the world. Of course, with the incredibly high prices of San Francisco, you'll be hard pressed to find something as good for the same price, butttttt well we still would've hoped for Airbnb to help find good and cheap(er) places to stay.

Thanks Phil!
