It's a room with a bathroom across the hall. The guest space was cleaned and set-up really nicely upon arrival. Hosts are very communicative and made sure to stay in contact with us before arriving and throughout our stay (house rules, check-in, accommodations, fun things to do in the area, etc.)
Only reason I gave it 4 instead of 5 stars is because it's not very private. Hosts sleep/work in the rooms next to the guest space.
