My wife and I travelled to San Francisco to run in the marathon and needed a place to stay. We don't typically like staying in "touristy" areas and this really fit the bill. The location is excellent to see all of San Francisco, but it PERFECT for seeing the less touristy, but (in my opinion) more interesting neighborhoods of the city. The apartment is clean, quiet, and very comfortable. The bed (sometimes hit and miss with Airbnb) was very comfortable and both me and my wife slept very well during our stay. Brian is very laid back, very welcoming, and available when you need him. He also knows the city in excellent detail and was a great resource for helping us get around. If there was one problem we had it is that we could not get to all the restaurant recommendations he had. San Fran is a food lovers paradise! I would not hesitate for a moment to stay there again. Do keep in mind that he has two rooms available and that they share a common (very nice) bathroom. So if both rooms are occupied, you will be sharing a bathroom with the other guest. This was not in any way a problem, just an observation for those that are picky about stuff like that. It was really a nice place to stay and was a key component to the terrific time we had in the city during our vacation.
One last piece of advice... Take an UBER if you are coming from the airport. We paid nearly $60 taking a taxi from SFO and paid $38 with UBER going back...
