Mathieu's apartment/flat is perfectly described. It is very close to shops, markets, restaurants, cafes and bars. As well as other points of interest (need). We took the subway from the airport to a stop that was a 5 minute walk to his home.
When we arrived everything was in its place and very clean. Prior to arriving, Mathieu kept in communication with us, answering questions and giving advice which was very helpful in getting around the city.
The location was perfect as well. Although I would describe Paris as tourist stop, we were not I n a tourist area. Rather 2 miles away from the places like the Louvre, Eiffel Tower, Seine and so on. Very easy to access by subway. Public transportation seems more like a right, rather than an accommodation.
I would highly recommend this apartment for all travelers but limit to 4. Remember, this is a small apartment. Very small kitchen/living area. But I'm grateful. I was reminded that life is meant to be lived outside of four walls and homes are meant for resting.
