I greatly recommend this place!
I unfortunately had issues with my account and wasn't able to communicate the couple days leading into our arrival which made planning our check-in difficult for them. Olivier and his wife really went out of their way to make sure they could be there when we arrived (not knowing when that was) or at least find a way to make sure we could get in if they had to leave.
All was great once we were able to connect. They offered amazing tips for restaurants, bakeries but also sightseeing. They were even ready to do our laundry if needed!
All the other reviews do include this warning - lots of stairs!! I had a 50lb suitcase and it was not fun. Olivier did help and I really appreciated did but lesson learned!
Location is amazing - RER straight from CDG airport. The neighborhood is extremely lively, and many great sights are walking distance. We had a great time!!
