Ryan is a great host-very nice and helpful.
His house is also very nice-clean and quiet.
The one thing that wasn't great was the neighborhood. It's a little sketchy. Overall, we felt safe. Plus it's close to the BART and about 3 miles from downtown Oakland. But there's a lot of abandoned warehouses with trash and graffiti in front of them, and some shabby houses (but also very nice ones!).
In general, I think this place is perfect for exploring Oakland and SF, and seeing how locals live. Wouldn't stay here if I had a family though, or for a romantic getaway.
