Beautiful spacious apartment in a perfect location! Don't hesitate on this one. Here's a quick run-down:

Location and getting around- Incredibly convenient and very safe area. In fact, more convenient than I expected. The RER train to and from the airport is a block from the apartment. There are also several different metro lines nearby. But, plenty of the most popular tourist sites are within walking distance (e.g. Louvre, Notre Dame, Rue Montorgueil) so you have many many options in terms of transport. There are restaurants and cafes right on the ground, with several supermarkets nearby. Some reviewers complained of the noise level of the nearby cafes, but we loved it and thought it added charm to the neighborhood and experience (and no we are not young adults, we are in our 40s and 50s!).

The Apartment itself- Very nice, comfortable, brightly lit, plenty of space. Very safe. Towels, linens, blow dryers, even a flat iron (!) are provided. We used all the appliances except the dishwasher and tv and had no problems. As three adults (one married couple and me) we never felt crowded. I slept on the pull-out sofa and slept soundly and comfortably every night. Wifi ran great, which was very important because some of us had to work from home on occasion. The apt is located on the second floor with a winding staircase, so don't bring your biggest or heaviest luggage. Otherwise you'll be fine.

Host- I called Catherine at the airport and she met us at the door upon arrival. She showed us everything about the apartment. Her and Dominique were altogether very responsive and gracious. One of my family members accidentally broke one of their dining room chairs and they were so SO NICE about it, I felt so bad.

Wrap-up: I would recommend this apartment to anyone who is interested but on the fence. The photos posted were 100% accurate. Good luck with your search and thank you Catherine and Dominique!
