I stayed in George's listing on my most recent trip to SF. George was very responsive to any questions I had, it is in a great location and has strong WIFI. The apartment itself was cold there was a heater in the hallway but it didn't heat up the bedroom. Unfortunately during my stay the upstairs tenants were noisy late at night. The area from the main door leading up to the apartment door was dirty and quite dated it could do with updating and passing by a large amount of shoes thrown outside the apartment door was not a pleasant sight however inside the apartment itself was clean. Overall I had an ok stay.
