Room was cute and small, but good size for just the two of us just needing a place to sleep. However, the space is not entirely yours. Yes it is separate and on the back of the main unit. But you can hear everything that goes on above you!! You also do you have any control of the temperature of the space as the main unit controls that so it does get pretty warm, especially in the middle of the night. If you are not a heavy sleeper, I would not recommend as you can hear every step from the unit above.
