I've never met a window seat I didn't love.Love this little secret nook of a room. the curved seat and round window compliment each other to create a perfect space! Would definitely read a good book here.
I like that each bunk area has some privacy and is painted a separate color (which obviously you could paint in any colors), but I might add a curtain to the sleeping area for more privacy. Interesting idea for a kids room where they have to share
two twin beds. A curtain hung from that cute heading would disguise your "bedroom" if you chose. A curtain would work above as well for either a bed or built in shelves and hanging space for your clothing; I really love the idea of deep, built-in beds
