Our stay at Catherine's apartment was absolutely great. We were there for 12 days. Absolutely no problems with communication, very easy to collect keys. The location of the apartment is great. It's not far away from the railway station (Gare Du Nord, ~ 10 minutes by walk) where you can get directly from the airport and metro station is in 5 minutes by walk. We've got detailed instructions from Catherine how to get to the apartment and some advices about shops, cafes. The apartment was clean and well prepared for our stay. At the apartment you can find everything you need (we even found oil, spagetti, salt, sugar :)). The district is quiet and there are some supermarkets. Thank you so much!
