F.K.
Small space can pose a challenge for painting/airbrushing, but easily enough handled. One issue in an apartment is compressor noise, but several are available that are small and very quiet. As to a booth, over the years I've used everything from temporary cardboard and plastic storage containers, to dedicated custom built version. Whatever works is OK, small, light and foldable is good, so it can be put away requiring minimal space.
Of real importance is exhausting the fumes. I use light material, wide enough to handle an exit hole for the discharge hose, tall enough to fill space from top to bottom of window or door frame. Open window enough to install the hose holder sheet, then slide closed to seal the window edge against the sheet.
That allows year round painting, airbrushing will really make your modeling efforts greatly improved. when compared to brushing or flit cans.
Mineral spirit paints are much stronger in smell than acrylics, likely better for use in your smaller space. Have a look on you tube, there are many examples of inexpensive and light weight spray booths, you can get some good ideas from them.
Good luck with it. Welcome to FSM.
