Daniel was super responsive to messages, and it wasn't a problem to give us alternative access rather than using the Kevo system.
The apartment wasn't ready when we arrived, but Daniel accommdated our early arrival by letting us drop our bags early before we went to explore. He gave us lots of tips on local places to eat which were all good (and were very welcome with jet lag!). It is quite far from a lot of the major tourist areas, but the F (for downtown), the 5 (Golden Gate Park) and the BART are all really handy. There are several nice looking deli type stores within walking distance too.
