The pictures don't do it justice - I had to put in an air mattress, and from the pictures, I thought it would be way too small but it fit in fine. The bathroom was clean and there's a fridge inside as well - not sure if that's the case for every room. In both buildings, there's a kitchen and in the main building, there's free coffee/tea/water. There was also body lotion and shampoo/conditioner.
We were unsure about the place because there were 2 listings with the same info/pictures so we thought it might be a scam, but far from it. They are actually an inn, and seems to be run by a family.
The closest station is the Davis station (about 5-6 min walk) - don't be fooled by google maps (sometimes it'll say that porter square is closer).
