The small studio under our house is simple & cozy. It doubles as our screening room so you can lay back with the door open, watching movies or the birds fluttering outside. In the morning, you can sit out beside the pool for breakfast in the sunshine. It's very quiet.
The bed is a sofa-bed and when out, does take up a lot of the room but it's comfortable & can be put away if you need more space. You have your own small kitchen and bathroom with shower.
