The greatest thing about this place is it's location. Not only it is has a side-view of Notre-Dame, but it is close to all kinds of precious and unique places that make visits to Paris so memorable. Thomas is a fantastic host, response time is just minutes. The little brochure with the personal notes in the apartment is very useful too, we have used quite a few tips from there. One thing to remember, the windows open on Seine, and there is a lot of street and construction noise [re-building of Notre-Dame] during the weekdays and parties and music till dawn at night (we stayed in June). Somehow, it did not bother me that much, although I am typically sensitive to noise. We had a great time!
