Raoni is a very nice host. Communication with him was always very easy and straightforward. He was quick to respond to any questions, and while we he was showing us the apartment, he reminded me a few times to call him if we had any questions.
The apartment itself is located in a quiet neighbourhood only a few minute's walk from three stations, two of which service the Rer B line, making it ideal for people coming from either airport. It is a ground floor apartment and accessible from a quiet courtyard.
The doors are all controlled by key code, so it makes it easier not to have to worry about a key to bring with you and keep safe.
The apartment itself, while small, is very well laid out and full of smart little ideas to maximise on space and provide functionality.
Raoni has gone to great lengths to make things easy for his guests, providing local information and scannable QR codes with information on how to use different things around the apartment.
There were 4 of us in the apartment (me, my wife, my 5-year-old, and my 2-year-old sons), and it served our needs perfectly. The proximity to Jardins Du Luxembourg was especially great for the kids and being able to get them out to run around for a few minutes in the morning. Additionally, it is about a 15-minute walk (with kids) to Notre Dame Cathedral, which is the centre of Paris, and you can access multiple areas easily by metro from there.
We will definitely be checking if Raoni's apartment is available for our next visit to Paris, and we would recommend you booking your stay with him also.
