We had a great time in Paris. Nathalie was helpful with preparations before our arrival, and flexible to provide early access to the apartment.
The apartment was very nice, even better than we could hope from the pictures. Well equipped and cosy, authentic city feel. We loved the open feeling and all the light, even though it's placed on the inside of the building complex.
Security is good with "key-less" entry (RF key), and the access from two streets worked well.
With 2 adults and 3 teens, we had all the space needed to crash for a few nights experiencing Paris. For our purpose we could probably housed one more teen if they could share the twin sleeping couch. If we should have needed to stay more inside (-why?, it's Paris! ), then the apartment might become a bit small even for the five of us.
Excellent, world class espresso place next to the building entrance, and easy to walk to many locations including the Louvre and Ponte Neuf.
We would come again, and recommend Nathalie and her place.
