Alexis was a gracious and friendly host. He had the place professionally cleaned for my stay and gave me a personal tour of the apartment. After that, he was always available on Whatsapp for any questions I had.
The apartment is spacious (for a Paris apartment) and easy to manage. Please note that it is on the third (American 4th) floor of a winding stair case. This wasn't a problem for me but it may be a little more difficult for some guests.
The location couldn't be better for someone who wants convenience and a central location. The apartment is surrounded by hundreds of restaurants, bars, boulangeries, and food takeouts. Just two blocks away is Le Forum Des Halles, a large shopping complex with every sort of store, including a grocery store (Monoprix). The nearest metro station takes you directly to and from CDG airport. Many major tourist attractions, including the Louvre, Musee D'Orsay, the Pompidou center, the canal, are within a scenic 30 minute walk.
For anyone who is looking for a base from which to explore Paris, Alexis's apartment is a definite winner. I was highly satisfied with my stay!
