We were a little tight fitting in the space, but I knew to expect that based on other reviews. It should probably say that it sleeps 4-5. There is one queen bed in a separate bedroom. Then in the common space is a futon (full size at most) and a large couch. We had kids so we fit two on the futon, one on the couch, and one in the floor on a sleeping bag. The house was really clean and nicely furnished. Kitchen was decently stocked.
Glad we brought sleeping bag, extra pillows, and plenty of food!
