Guillaume's apartment is great! It's located in a nice area with several metro stations within walking distance. He has given us some tips about nice restaurants and bars in the area. The apartment itself has lots of natural daylight and nice design furniture and decoration. We have stayed there with one couple and a friend and it's large enough to have some privacy. Last but definitely not least, Guillaume is a very friendly and hospitable guy. Further, he responds to emails and texts very quick. We will definitely check if his place is available once we plan our next trip to Paris.
