The identical "twin-size sofas" are 5'7" long and about 4' wide, have an uncomfortable uneven and hard surface, and during our recent stay one of was unusable due to a broken/missing support. The air mattress is a good stopgap but the apartment therefore truly only sleeps a maximum of 4 people comfortably. The windows unit A/C is in the bedroom, and when the bedroom door is closed, cooling is a bit uneven in the rest of the apartment.
