This was one of the best places I've stayed at on AirBNB and I use AirBNB quite a bit. The space was perfectly located 2 blocks from the BART station. The room was spacious with its own ensuite bathroom. The room and bathroom essentially had everything you would need and more. Much better supplied than any hotel room I've been in. His apartment was immaculately clean. Mark was also a wonderful host who responded quickly to messages and always offered coffee or breakfast in the mornings. I was pretty busy the entire time I was in SF and didn't interact with him as much, but he was always willing to help and offer any assistance.
I would gladly stay with him again if I'm ever in SF. Would highly highly recommend!
