I think this was designed for a pre-teen/teenager, but there's a lot I like for a guest bedroom/home office. Love the built in desk and storage and love the blue, white, bright green color palate. The ceiling fixture is especially cool.
I like the high shelf above the bed. Still gives you a place to keeps things while still allowing you to sit up in bed to read and such. Plus I imagine that having to actually sit up to turn off an alarm would help you wake up in the morning.
