We arrived at Gare du Nord and went by foot to the apartment. It was really close to Sacre Couer- you can see it from your street- beautiful view! Sylvia was really nice and sweet. She offered us to keep an eye on our luggage before check in time bec we'd arrived really earlier. That was really cool!
She didn't speak Englisch well but this wasn't a big deal! The apartment had a everything you need and it was clean!
It was on the 7th floor so it wasn't loud and you could sleep until 12 pm without being interrupted by car noise or something like this.
We had a pleasant stay and for two people it was the right thing :-)
