The location is good! The apartment is away from the main street and any busy areas so no problems with noise at night. There are also alot of grocery stores, bakeries, bistrots and cafes in the area. The apartment is very close to the Canal, Parc des Buttes Chaumont and La Vilette park, so if you enjoy having a drink by the canal or a picnic during the day without going far its perfect.
The M7 metro has stations very close to the apartment, and if you end up having a late night in Pigalle, walking home is also not too difficult.
The apartment itself is old and rustic, decorated with posters and filled with music and art books by Olivier who is an art producer. Olivier himself is very accommodating for any extra needs and flexible if you have a late check-in. The house mates are also very accommodating and friendly, there was an instance where i forgot my key and they let me into the room at 4:00am! without complaints.
Keep in mind the room permits smoking, the amenities are very basic and the house is a bit old, stained and rustic, nothing modern, super clean or fancy. There is a large shared balcony with a table and seats which makes a nice sunny spot for in house breakfast.
So overall it is perfect for young non fussy travelers that are on a budget and want to avoid touristy areas and live in the real Paris. :)
