Me and my family had a nice stay at Boris place. It's located in a lovely area of Paris within walking distance of a lot of interesting sites. Communication with Boris was great and he was quick to respond any concerns. But there are a few things that could have been better. For instance, the apartment was very poorly cleaned upon our arrival and we had to clean it ourselves. Also the kitchen could have been better equipped (there were for example no kitchen knives).
The accommodation is perfect for 2-3 people but it was a bit too small for a family of five.
