Romain was very nice when he welcomed us personally in his appartment. The appartment was clean, the bed was comfortable and the shower was warm.
It is a cool, bright appartment with 6 windows and in front of a nice café-bar. It is a nice feeling to come home, open the window and sit in the living room having the feeling you are still around but with a privileged view and privacy :) The music facility does also help for improving this nice feeling, also in the morning in coffee time.
the region is full of life, you have Edit Piafs museum very close, on Saturday a very nice flee market in front of the cemitery Pere Lachaise and nice cafés and there is one hidden bakery which is amazing, but maybe you can ask Romain to explain where it is (in front of a bus station and very small).
There is one single issue I consider important: he forgot to mention (probably because it was his first time hosting) in the description that it is a smoking apartment, and it may eventually be annoying for those non-smokers who are more sensitive like me (my boyfriend didn't care at all).
