This is a great downtown location - close to the Powell St cable car, walking distance to the BART, and only a few blocks from a great saltwater swimming pool at the Chinatown Y. AC was supergenerous - leaving us snacks and mini-toothpaste and shower gel (which we had forgotten to pack!). He also checked in every now and then (by text) to make sure everything was OK - even though we didn't meet in person, it was great to know we could call on him if necessary. The apartment is small but (for us New Yorkers at least), not that small - it easily accommodated my partner and I and our two suitcases. It's also clean and quiet, and looks nicer than in the photos! In short, I highly recommend this as an affordable place to stop in SF. A great all-round experience.
