Clelia where very friendly and answered my messages very quick. She sent me a folder with some informations about the apartment, the check-in and how to get there. We got some tips about where to eat, the stores and the public transport. Since we checked in very late (around 10 p.m.) and checked out very early (5.30 a.m.) we haven't seen Clelia and Alexandre in Person, but the check-in was very uncomplicated because of the key box. The apartment was clean, there where fresh sheets and towels and it was fully equiped with a coffee machine, a washing machine, dishes and all the other things you could need during your trip. From the airport Charles de Gaulle we got to the apartment with Uber, which took us 25-35 minutes and it costed 36€. You can also get there by bus or RER, which will take you 50-60 minutes. From the apartment you can get into downtown within 15 minutes with public transport. If you want to go to Paris for a trip, I can warmly recommend Clelia´s and Alexandre´s appartment!
