Reminded me of a hostel, decent budget option.
The bedroom itself was good/clean. Small but cozy, with multiple space heaters, towels, a desk and big empty drawers. We had to walk downstairs to use the shared bathroom.
The walls/floors/etc of the house were dirty and most of it had a strong bad smell, kind of moldy maybe, that made it unpleasant to spend any time outside the bedroom. There were signs saying it was a "shoeless household", presumably to keep it clean, but my socks became very dirty and covered in debris walking just up and down the stairs/in the kitchen. Slippers were provided at the front door which is a thoughtful touch, but they also were dirty/stained.
The bathroom was cluttered and a little dirty but I've seen much worse. Hot water in the shower worked but not the sink. Kitchen too was cluttered, a bit dirty, but could be much worse.
He was very upfront about it being an old house with no heating, which was no problem because he provided space heaters.
