Nice apartment, great place. Little maintainance needed. Superb host, quick communication and problem solving.
You should be aware of the lay out of the apartment (difficult accesable bedroom in the cellar) and the fact that the apartment is noisy. Don’t go there if you want to stay a lot of time in your apartment.
But for exploring Paris it is a great place. Perfectly located next to Sacre Coeur/Montmartre
