The place is very nice and close to the metro. The walls are really thin and you can hear everything, even when someone enters the building (even though the apartment is at the second floor :) ).
Communication with Caroline was good and the check in was smooth.
Caroline and Adrien live in the house and we felt a little uncomfortable with all the rules of the house (take your shoes out at the door, leave everything in the same place, etc.) - we felt a little bit like unwelcomed guests. We tried to follow all the rules and we left extra coffee and stuff in the fridge (because the rule is not to consume their stuff), but it was rather tiering :).
I thank them for their hospitality, but I prefer more relaxed places.
