As stated in other reviews this is a delightfully charming artist apartment just steps from the Basilica. It is very spacious by Parisian standards and had all of the amenities we needed. Nathalie provides clear instructions on what is available for guest use - you literally can just show up with your bags and feel right at home.
Nathalie’s communication was excellent both leading up to and during the stay, and she was prompt to respond when we had a problem (the cause was not under her control but she went out of her way to fix it).
One note for very light sleepers who turn in early - the apartment is above a lovely square with several excellent restaurants so it can be noisy in the evenings. Nothing that earplugs couldn’t fix. This was the perfect Parisian getaway in my favorite part of the city!
