We only stayed in paris for 2 nights and had a wonderful time at Mathieu's place. It is very cozy and nicely furnished, exactly like the pictures. He prepared everything perfectly and made our check in very comfortable and easy. He also replied immediately when we had questions or problems. He really cared that we have a good stay at his place.
The apartment offers everything you need. The location is perfect, just a little walking distance to the nearest metro stations.
We are perfectly satisfied with our stay in his flat and would stay there again when we're back in paris.
