I am so glad I asked you in time, ladies!
The results are astonishing! One bedroom is not enough, two is not really convenient – I got it. Before I was thinking about a loft on the second floor but after I tried to count your preferences I saw that 13 of you prefer the first floor. So it is much more likely to be a family room about 20’x 20’ft in size, no less! It should be sunny and have enough outlets and even overhead plugs. Still some of you “prefer a room with a door I can close if it's a mess” but sadly family rooms usually don’t have this option. As Halo sad earlier “that would be a good reason to make a quilted curtain to close it off.” Or I can put up a few dividers to border the area, if there is no possibility to hang the quilt from the ceiling. So be it, for I am house hunting again!
