The place did match accurately the pictures, it was clean and amenities worked well. Jason wasn't present when I arrived but reachable. I believe check in instructions will be updated to add the bit of information that was missing when I arrived.
I didn't find much to do in the neighborhood and the streets tend to be relatively empty, but I was mostly looking for a short commute to San Francisco. The walk to the West Oakland BART station took me around 7min, and I was in roughly half an hour in SF which was perfect.
Note that it is a basement, it is very well lit when the lights are on (again, the pictures are accurate), but of course there is no natural light. I hadn't really noticed when booking, don't miss it if it makes a difference for you!
I stayed a week and it was a satisfactory (as in good) stay.
