Nice apartment, clean and perfectly usable. Leon is a great host.
The room itself is quite small but should be enough for one person. Bed may be hard to climb up to.
The only real issue I had was the temperature - it was quite cold in the room, there is only one small electric heater that I wasn't allowed to turn it up above 21c, and it made the room quite cold at night.
Other than that, can definitely recommend the space.
