We had a lovely time staying at Charles' apartment! The location is great, in an up and coming, trendy neighbourhood with lots of little treasures to find. We are big walkers, and we're able to walk to most of the sites of Paris from this location (long walks, but worth it...) The apartment itself was clean, stylish and well maintained. We were a group of 5, and all slept comfortably. Charles was an excellent host who stayed in constant contact with us. He was very responsive to questions as we stayed, and even messaged us local goings on.
I would definitely recommend this apartment to friends and family, or anyone else looking for a place to stay in Paris. :)
