The place is ideally located, steps away from la Bastille, so everything is at a walking distance.
The apartment is in an old building, so expect the pros (charm) and cons (not very functional) of this kind of place. Altogether, I was fine with it.
Now, there is a lot of Xavier' personal stuff in the apartment, including non-functioning ones. I would suggest him to do a deep cleaning and remove some of his stuff. I would make the place much more desirable. My 2 cents.
