We had a lovely stay in Paris.
Quentin was very flexible and easy to communicate with. We arrived an hour late, but apart from a 10 euro fee (as expected), there was no trouble.
Our time spent in the apartment was limited, as it was our first time in the city and we spent most of the time exploring. I would recommend the place to anyone with the same intentions. The location is great and super close to a metro station with two lines. The room and bathroom are spacious and Quentin kept the place clean and tidy.
Keep in mind that there are no locks on the doors to the room and that you share the bathroom with both Quentin and other guests.
