First of all, Carole's apartment is been nicer than the pics. Everything is clean and nicely designed for friendly use. And you've lots of spaces for your bags and things. You can simply enjoy staying at the apartment if you don't want to go out. There are lots of interesting books. It's equipped as a top rated hotel but feeling home and cozy. Very nice and spacious bathroom and you can even enjoy a bath! It's rare find in Paris.
The location is perfect where you'd enjoy a local decent Parisian life but avoiding touristy ambience. 5 mins walk from metro and you can simply walk to Notre Dame and other key locations in 15-20mins. Very nice restaurants nearby. A safe and decent neighbourhood.
Per my interactions and email/text correspondences with Carole, it really tell why she's a super host. Prompt response with detailed info even on small little things. Carole met me downstairs and kindly showed me the apartment and building. She also helped me to arrange a cab upon departure and offered me/my friend a drink (but unfortunately, our schedule was quite packed and did not make it happen). Carole's in the same building and it's always an advantage and helpful if you need urgent assistance, especially if you're travelling alone and first time visit. I'd definitely come back in next visit!! Highly highly recommended!
