We really enjoyed our stay at AC's apt. He was very efficient in the booking process, gave us clear instructions about his apartment, provided us with travel guides about the area that ended up being really useful, among other things. His apartment is in a very central location in a good neighbourhood, within close proximity to the BART subway, downtown, Chinatown, Japantown - we walked to all of these areas - even to the Marina to the north. The apartment was in good working order, and we appreciated the coffee machine in the mornings! Thanks AC!
