This was a good stay. I spent a long stretch here (36 days I think). Chiz is quiet and a good host. The room really is very big. There is a nice space heater if it gets too cold. The room can be a little dark in the mornings, but I never had a problem.
The stairs do open directly to the living room above and there is some sound spill, but the room is still very private. Chiz is quiet and I almost never heard him upstairs even without a door.
I did need my own blanket and towels, but that's pretty clear from the listing.
This location is also great. Walking distance to Prospect Park, Brooklyn Botanic Garden, the A/C subway lines, LOTS of great food.
