My boyfriend and I stayed at Julien's house for 5 days in the end of winter! The experience was great from the beginning - Julien is very thoughtful and attentive.
The apartment is very comfortable, clean, heathing works perfectly and the shower is great!
It's a popular area/street but we've found it very safe and secure.
Very very close to the metro station and to Montmartre and Sacre Coeur!
We would definitely come back when we go to Paris :)
