My mom and I stayed at Vincent's flat in mid April for five nights.
We had some few unusual issues such as door unlocking and water leaking problems but overall, that's so not unusual in Paris that those didn't really bother us much as Vincent was very responsive and was flexible to deal with the issues very quickly.
The flat was so comfortable and relaxing - moreover the location was great to get around and we felt very safe!!
Vincent was very nice and responsive that I'd definitely recommend staying here.
