We stayed at Vincent's place for 5 nights and had a really pleasant time there. The room was very clean and well-equipped, the bed was comfortable and the internet pretty fast. Unfortunately, Vincent was busy most of the time, so we only met briefly the day before we left.
In the kitchen there was everything available for cooking, which is nice if you want to prepare your own meals instead of buying the expensive food in Paris. Next to Vincent's apartment are several places where you can eat Sushi, Pizza or more traditional French food and there is a supermarket right next to the flat, which was very convenient for us.
The only thing that was a bit surprising was, how thin the walls of the building are. You could hear the neighbors really well and whenever someone flushed to toilet or used the kitchen oven. So if you plan to go to sleep before midnight or after 9 AM, better bring ear plugs. ;)
