The only issues we had was the windows are the original shed windows which don’t seal well. Someone in the area was burning a fire and I smelled it all night because of the windows.
A futon is not great for sleeping on in any condition, they just are not comfortable. This was not the exception. So I wouldn’t advertise it as a sleep sofa. It was fine for sitting.
The area is nice with nice views and very close the the boat landing, so is a great location. Easy set up for charging the boat battery.
