I painted my apartments semi gloss because the paint cleans up so easily but the shine will show imperfections. I'm not working on changing the walls to a satin finish. If you used oil paint in the bathroom and kitchen, don't put it in your bedroom. Latex does well everywhere and is so much easier to handle. You also have to be careful with whatever is on the walls now. Most paints peel off if painted over oil. Like I said I used semi gloss and everyone laughed at me. My very first person to look at the apartment just loved it. I ended up painting the same paint over the kitchen cabinets after sanding them a bit. The paint stayed on and again...easily touched up. It looked so much cleaner and nicer to have the cabinets match the walls...small kitchen and visible from living room...just do the prep work before painting. I should add I ended up painting everything a white with a bit of yellow in it and years later I can go back and get the same color and just touch up the walls and that's with a semi gloss.
