If you are reading this review, book this place!
Everything is exactly as it looks in pictures - I would say even better. It is a very spacious room and I loved having my own private shower and bathroom with plenty of hot water. The bed is big and very comfortable, and there are plenty of outlets for all your electronics. Windows face into an inner courtyard, making for a very quiet and peaceful stay. Camille & Mario's place is located in a very desirable and active neighborhood with plenty of cafés, restaurants, and bars, and within a short (less than 5 minutes) walk to various metro & bus stops, including the large Chatelet-Les Halles hub - with such easy access to transportation and not to mention being only a (less than) 10-minute walk from both the Louvre and Notre-Dame, you are really in a pretty perfect location.
Camille and Mario were incredibly responsive to all of my questions as well, helping to make this one of my favorite Airbnbs!
