It is all abut the expectations.
If you are looking for a big flat with nice views, cool apartment, very comfortable and trendy wishing for a place with more than 1 bed, this might not be your perfect choice.
But if you are looking for a very kind, friendly and quick responsive host, a place where to spend night and discover Paris, be in the heart of cafes, markets, restaurants, public transport to literally everywhere, and gonna stay as 2 person, this is the very right place.
I stayed with my son for 5 nights in Yves's place and it was truly a magnificent point to stay. We went to everywhere (From Eiffel to Disneyland) from the walking distance station (Chatelet), visited Louvre by walking, discovered many supermarkets and cafes just around the house.
Adding on top of it the smiling kind attitude of Yves just made this experience even better.
This small but lovely place will always be my second home in Paris.
