I would give this Airbnb 5 stars for it's location! It's very close to beaches and the Golden Gate park. Going to downtown is also easy, since there are many bus locations around.
Alex (the host) is a very friendly chinese man. You might see him during your check- in process. If you don't see him, he replies to your texts very fast.
Be aware you will share this airbnb with a lot of other people! Unfortunately in the next room to us stayed a family with little kids - houses here in the States have very thin walls!! Be prepared to sleep with ear plugs.
The bathroom is shared too - not a big problem for us though. It was just a little dirty.. Alex you might consider cleaning it from time to time.
Overall it was a decent stay. We only slept here for 2 nights - so it was okay!
As I said, the location is great!!
