I highly recomend to stay with Dominique. His place is super clean, beautiful, cozy and has impressive view. The apartment is definely near the La Chapelle station (2-3 minutes +/-) making it a really cheap and good place to stay.
Talking about Dominique itself, he's a really nice person and extremely helpful! He really take it serious, he has a book full of atractions to go, including map and price!
I'll be back to Paris and I'll choose his place to stay, definetly!
