The space is comfortable but the bed is not (needs a mattress topper as you can feel the springs of the bed). The space heats up quickly when using the radiator. I didn't end up using any of the kitchen facilities, but I expect they would be easy to use.
As a heads up, make sure you plan what you want to do in town before booking an airbnb. I didn't plan ahead and ended up with 20+ minute commutes via metro/train/bus to things I wanted to do in the city.
