Mathieu was a great host, very communicative with good advice. The apartment was very clean, and the listing is a true reflection of what to expect. We found it easy walking to major attractions, Sacre Coeur, through Montmartre in one direction and the Louvre in the other, but the apartment is also very close to 2 metro stations. Opera is a lovely area and we felt very safe both on the street and in the apartment which is very secure and quiet.
