We're lucky to find Fabien's place as our host as soon as he published his listing! He replied very quickly and we were able to get in the place just in few hours.
The apartment is in old classic parisienne building, I liked it! But the elevator in the building is too small even for one)) There was a lot of space for two in the apt. The flat was clean and prepared for guests. Small but cozy kitchen, nice living room and a big bed in bedroom. It's very easy to get, just in 5 mins from Gare du Nord, which was very good for us as it was raining in the morning we left. Sometimes it was noisy because of the station but it didn't disturb us much.
From the apartment you can get Montmartre just in 15-20 mins by walk, and Sacre Couer is visible from the street :) It always was 'wow!' for us to see it on our way back home!
