It is a cozy studio space with a clever pull out bed and a nice balcony for morning coffee or evening wine. However, it is a long walk (or 5 min velib bike ride if you're lucky to find an open bike at the station) to nearby shops for coffee or wine in order to enjoy it. If you are open to a 10+ min walk to the metro or relying on Uber this is probably ok.
The raised living room/sunken dining room is very nicely designed, however, the pull-out bed is very uncomfortable. My partner and I removed the mattress from the slide-out and slept with it on the floor which was much more comfortable.
As a studio space with only 1 room to sleep and get dressed, we were surprised to wake up to a message that the host was popping-in in the morning to get something. We only had a few minutes to make ourselves decent so we decided to step out for breakfast, she was then completely unresponsive about if she had ever come in or left despite that we gave clear times about our plans.
With the strict 10am checkout due to another guest arriving, we ultimately decided to leave early to get a hotel in a more central area. Doing this was less expensive, more conveniently located, more comfortable, and allowed us to leave our bags so we could easily enjoy Paris until our evening flight back to NYC.
