Alex's place is absolutely wonderful! He and his team are extremely responsive and kind in making sure we had a great stay in Paris. I'd definitely recommend taking him up on the car service to the apartment from CDG (all of the drivers were extremely kind AND PROMPTLY ON TIME!).
The bathroom is a little tough to manage with a group (the toilet is situated in a room behind the shower, so if someone is showering you'll have to wait to use the toilet; also, the shower has a very low ceiling), but we made it work with a group of 4 petite girls.
I would definitely recommend staying here for a couple or a small group, and hope to have the privilege of spending time in this beautiful space again. Merci beaucoup Alex!
