The location is close to the Les Halles station so is very easy to access Paris public transportation. You can take RER line B to CDG airport.
Mario&Camille were very responsive for our questions and actively asked us about our itinerary and check-in time so they could get the room well prepared. The normal check-in time is in the afternoon but we were able to drop our luggages there in the morning.
The room for guest is exactly the same as what is mentioned on Airbnb. The guest room includes a private bathroom, which is very clean and easy to use. The bath towels are also provided for each guest.
Mario&Camille also provide a website which includes very useful local tourism information, including restaurants, google routes for visiting Paris and other very guides of Paris.
It is safe staying at Mario&Camille’s home. After we leave Paris, Mario&Camille found that we had left a pair of ear rings and a bracelet in the room. They sent us message immediately even before we were aware of that. And then they mailed them back to us. Really appreciate them!
