Vincent was excellent from start to finish, for sure one of the best I have experienced.
Pros: (there are only pros)

+ Timely communication, including updates and reminders one month ahead of our visit to ensure our questions are answered and plans can be made. Vincent answered my questions perfectly, including supplemental directions to the flat and questions on check in/out. Vincent was always incredibly friendly and approachable if I had questions.

+ Location, fantastic location, close to some very nice non-touristy areas for eating in the evening and sitting for a coffee. A stone's throw away from all of Paris's major attractions, we walked the entire time (except from the train station, which is doable but we had a bag). Very quiet too, we slept soundly every night.

+ Property, very very clean, certainly the most well kept apartment on airbnb we have stayed in. Good facilities (fridge, tv, wifi, shower, washer [we did not use]) and the lights/bedroom area are very cosy. We would definitely stay again. One minor thing, the property is on the 4th floor without a lift, so check before if you have any accessibility concerns.

Overall really enjoyed the stay, the communication was great and would definitely stay again.
