Essentially I have a 3 br town home. The bedrooms are quite small. I have one bedroom setup as a master (my wife and I) with a full BR set (Queen, dressor, mirror, nightstand and chest) and the 2nd bedroom setup as my daughters room (it's the smallest). I have another bedroom that is kind of inbetween the sizes of the largest room and my daughters room. I'm not quite sure as to what that room should be used for. My study is in the basement (computer desk etc...). My wife wants it for a guest room. But she wants to put another small BR set in there. I don't feel comfortable with a bed in each room. I kind of want to do a study/br/activity room. Kind of like a sleeper sofa on the longest wall with bookcases all around and a small computer workstation in there. Kind of like a multi-purpose room. What is the 3rd and no use room commonly used for?
