Great experience!
Regarding the flat: great views (you can see Sacre Coeur from the windows) and everything completely clean. The bed mechanism worked at perfection.
The flat is perfectly communicated: train station, RER B and D and two different Metro lines in the surroundings.
Regarding Pasquale: great host. He helped us in no time with a couple of issues we had over the weekend, specially when my girlfriend got sick and he rapidly arranged a visit to the doctor (on a Saturday!) for her to get checked.
Highly recommendable!
