This place is bigger than it looks in the pictures and while it's an old house, it's got fabulous character and it's quite comfortable.
The bed is moderately firm and comfy - so is the extra pull-out bed. Way more comfortable than it looks. The kitchen is decently equipped ... be careful with the knives, though, as they could use a good sharpening. The shower is excellent - I loved the body wash, too.
I understand the neighborhood might not be for everyone, but I loved it. I walked around quite a bit and met lots of friendly people. The owner of the laundromat a few blocks away even let me stay an extra hour after closing to finish my laundry.
The only downside was the heat! Of course, the owners have no control over the weather, but if you're visiting during a heat wave, the place gets quite stuffy and hot, so be warned. In Oakland, though, that's rarely a problem.
