This place was perfect. There were two adults and we both had a sense of privacy while also enjoying the place because of the two beds. It was perfectly located to everything including metro, buses, Hop On Hop Off Tours and walking. We walked to just about everything we wanted to see in the city.
Jean and his wife Jess were fabulous, kind, responsive and helpful. There were clear instructions written in multiple languages for the unit. WiFi worked great as well. The only negative is you only get one key and it's the only way into the unit. So if you dont do everything together it can be a bit inconvenient as someone is always waiting for the other to return. It would have been nice to have a 2nd key, especially if someone lost one or locked one inside by accident. However, there is a lock box outside the door and you can leave it there which we didn't discover until the last day. That was our fault for not reading all of the instructions on day one. :(
The bathrooms were a bit small and odd in that the bathroom in the bedroom had the shower and sink but no toilet and the bathroom in the livingroom had the toilet and a sink but no shower. While at first is seemed strange to me (as an American, perhaps that's normal in Europe), it actually worked out perfect! One could shower while the other still had access to the toilet, mirrors, brushing your teeth, etc.
The best part was literally looking at the beautiful Notre Dame everyday right from your bed. Is was magical, especially for this being my first time in Paris. We're could open the windows for some fresh air and to simply listen to the neighborhood, which we enjoyed. There are a lot of clubs near by so it could get rowdy at night, but if the windows were closed, we really could hear anything except the occasional police siren. And we actually found it entertaining to watch all the activity from the unit.
Thank you to the hosts for your hospitality and quick responses. I will be back and will recommend this to all my friends. It was an amazing vacation.
