Matthieu's room was very small, but if you don't travel with a lot of luggage and just want a place to sleep, it's perfect and it has got all you need. The murphy bed is very comfortable with nice linen, and the bathroom is quite modern.
A big plus is the individual check-in with key box which is great when you want to be flexible. What really helped me was that I could drop off my luggage before check-in (which is very rarely the case if you don't stay in a hotel but in an airbnb flat) and leave it there after check-out. It is stored in a safe place. The fact that there is a reception is great for a single female traveller.
I can recommend Matthieu's flat for anyone who wants to be flexible and independant and travels light.
