As with many other tiny houses, this one makes use of a loft to offer additional sleeping space.
The kitchen actually looks to be surprisingly spacious. It is hard to get a feel for scale with this photo, so it may just be the layout which is creating an illusion of space.
Either way, that is a lot of countertop to work with, so if you feel like cooking up a storm on your vacation, you can.
The bathroom is simple but functional.
