I and my girlfriend came to Paris for new year holidays, so we looked for a nice apartment in the center of the city. When we just came in we were surprised how amazing is it. In real life it even better then on photos. When you stay there you fill like you are at home because of some cozy atmosphere. Also it was surprisingly for us because everything you need is already there for you (even an umbrella which was super handy in a rainy day). Infrastructure is also very good - there is a Monoprix (local supermarket) and metro in 5 mins by walk. Also there are a lot of different bars/restaurants in nearest buildings. One thing that could be a problem for someone is a noise at night. Nearest streets are quite noisy (or maybe it was like this due to the new year holidays) so if you are looking for a super quite place it may be a little problem for you, but as for me it wasn’t a problem at all.
Unfortunately we didn’t meet Francois, because he didn’t have a chance to do that, but it wasn’t a problem - his friend Elise met us and showed everything. Also I want to admit that Francois is super responsive so if you will have any issues he will help you immediately.
