We had a great stay in Krystell's appartement, it's very centrally located close to metro and on walking distance from Gare du Nord. The location near the Sacre Ceour is beautifull and lively in the evenings. The communication with Krystell was very good.
The appartement itself is nice and authentic, only point of improvement could be the communal spaces and staircases which could use some maintenance.
Thanks for Staying!
