Working from an apartment myself, I've heard a lot of people recommend this. One of the downsides though, is the curing time. I've been coating a pepakura in cool weather (below 20 celcius) and it took four days to cure. So, I'm going to add patience to the list. If you don't have a shop with spray booths and lots of space, you might have to just wait for warm weather.
Well with polyester and/or epoxy you could also make a small heated chamber (with light bulbs for examples ....) I made my first one using expanded styrene sheets, they work very well and they are really cheap.
At least for my experience, I started making props in my first apartment, i had a dedicated room (bedroom..) with some desks, etc ... I have done all the painting stuff on the balcony, but as said previously it's limited when the weather is convenient, and winter is really bad for it ...
I made the same, in my second, and third appartements, I always had balcony's, but as each move, my so called "Workshop" expanded ....
Today I'm in a house, with a "small (12 square meters)" garage and a garden, in spring/summer I do most of my stuff outside, but for all the other seasons, I work in my spare bedroom, which is also my main workplace, I have tables all around the walls and wall mounted rack shelfs (they are cheap, easy to mount, modular, etc .... and can handle lot of weight) well under each tables I also have drawer's towers
Well here's a small pic of some of my latest workspace

At least my big tools are now located in the so named garage, cnc, 3d printer, drill column, circular saw etc ......... and also a paint station ( made from extruded styrene sheets too ... for the hell winter)
As I worked for a long time, and many places in appartments, I managed to deal with props making in a "bedroom", and how to deal with small spaces, I also build a suction table for the sanding work (but I still wear a mask every time and my apron, sanding can be most harmful than the resins themselves ...)
A good thing to have is an air purifier, like the alcion p100 ( 200$ / 20 square meters ) / alcion p200 ( 900$ / 35 square meters ) depending on the budget, it's to clean resin vapors unless you can open the window when working (or in the winter)
Well

want to read next experiences !! need more tips too
