We only met Brigitte briefly, but Guy was very accomodating and helpful when we asked about getting around the city. They speak wonderful English if that is important to you, the most French I know is how to say "I'm sorry, I don't speak French. "
In this instance, they didn't have a reservation for the apartment after us so they let us stay longer than the check out which was unbelievably lucky and kind of them or else we would have had our bags around Paris with us until our 19:00 train!
The apartment is very lovely and as pictured in the listing. The amenities are great, but it really is a small studio. Apart from the full 4 piece bathroom, it's a one room studio with a kitchen corner. No where near uncomfortable for 2 or 3 people, but be aware. Nice view from balcony and you can see the top of the Eiffel Tower just behind a building,
It is very close to the metro and lots of shops. Some maps and resources are available for your use which is very considerate.
We had a wonderful time in Paris made comfortable and stress free by Brigitte and Guy and their lovely studio apartment.
