Christian was really great. I arrived late to SFO airport and texted him when I landed. By the time my Uber arrived at his place, he was waiting for me outside to help me get into his place. I might have had trouble finding his apartment if he hadn't been there so I really appreciate him helping me with the check in. The place itself is cozy, very well furnished and very clean. It is exactly as shown in the photos. For a one night layover it was perfect. One very minor issue is that the water pressure from the shower is a little bit low, presumably to save water. I also experienced the shower water temperature getting cold every minute or so, but it wasn't a big deal for me.
The location is pretty residential and it's not that close to train stations or other public transit, but it is easy to get to the nearest station or zipcar parking spot by Uber. If you drive there is plenty of street parking.
Overall I had a great stay and would recommend the place!
