Lovely flat overall, the room is cosy and has a nice view of the Sacré Coeur Basilica.
The location is very convenient: 15 min walk to Gar du Nord and 5 min to the nearest tube/metro station, Montmartre nice bars and restaurants including the Moulin Rouge are within 10-15 min walking distance.
Elisabetta is a great host, very welcoming and friendly, and gives good advice and suggestions. Really had a good time during my stay in Paris.
