The apartment is spacious and very well decorated. It has a great tub for soaking. In addition, it has a washer/dryer, which we used a few times to clean some accidents our baby had. We felt safe in the apartment and the dark out blinders made it easy to fall asleep. The owners are very environmentally minded, which we really appreciated. They went out of their way to provide spare baby gear, which really saved the day.
The apartment is centrally located in Oakland, which means that the neighborhood is going through a bit of gentrification (I only mention this, since we were not expecting it and with a baby it did not feel appropriate to walk at night. You may see nice areas across the street from not-so-good areas). I would recommend having a rental car, or using Uber/Lift.
It is heated by a gas wood-stove, which we forgot to turn on the first night, so we were a bit cold, but that was our fault.
