We enjoyed our stay in Paris at Thierry's apartment. It is in a great neighbourhood, safe with everything you need nearby and walking distance to the Metro station so it is very easy to get everywhere you need to go.
The apartment is on the fourth floor with no lift, so we did make sure we had everything we needed when we went home for the night! It is small (standard for Paris) and simple but was just what we needed. It is newly renovated, nice and clean and has aircon.
We unfortunately didn't get to meet Thierry in person but communication with him prior to arrival was good, and he had a friend greet us who was friendly and helpful.
I would definitely recommend staying at Thierry's apartment. Merci beaucoup!
