Elene and Jacques are very friendly hosts, sociable, quick and informative by e-mail, keeping in touch by SMS. Although we have not met in person, thanks to the very detailed instructions we had no problems to get to the apartment and get the key.
Inside the apartment we also found a note with detailed answers to all "FAQ": where to throw garbage, how to connect to WiFi, where to buy the food, and so on and so forth. It was very convenient, just awesome :)

The apartment is located within walking distance of many attractions, there are a couple supermarkets, a lot of cafés and shops. On the station Chatelet+Les Halles several metro lines are connected, and there is RER B stop (to the airport Charles de Gaulle).

Apartment is small, but we comfortably settled there all three (adults).
A quiet room, no noise at night. The kitchen is equipped with everything needed for four people, very clean. Conveniently, the toilet is separated. Bathroom comfortable, although in the shower a lot of water collects in the pan, the water flows away very slowly.
WiFi signal is stable, enough electrical sockets for our numerous electroni gadgets :)

I am very grateful to Elene and Jacques for their hospitality and highly recommend this apartment to friends.
