Nicolas' flat is in a very convenient position and it is perfect for someone who wants to visit Paris and is not planning to spend a lot of time in the flat . The flat is quite nice, perfect for 2 people, but we were 3 friends and for the 2 nights we were there, the sofa-bed was more than fine as well.
Nicolas is friendly and he cares about his guests, which is always good.
Overall, also considering the convenient price of the flat, we decided it was a very good deal!
