Our family of 5 (parents & kids aged 14,11 & 2) stayed at Charles' apartment for 3 nights. The space is very charming and the building is beautiful. We loved the neighborhood & enjoyed choosing a new patisserie for breakfast each morning. We went up near Sacre Couer 2 nights for dinner and loved the vibe up there.
Charles provided a cot for us which was very helpful for our littlest. I don't think the apartment is very good for little kids though, because the neighbor downstairs came up to complain our first morning that my toddler's feet were too loud.
Also, showering was tough because there is no place to put the hand-held upright. Baths were the best way to go. The couches that converted to beds worked well for the big kids.
Charles' communications were great and he is very organized.
Overall we really liked the space and the location was wonderful.
Thanks for having us, Charles!
