We are a family of 5 and we have stayed in Adrien's flat twice in Jan and Feb. I would like to say that is was the best selection we could have done! It was a great experience.
The first time we were received by Paul and the second one by Pierre but we also met Adrien there. The three of them were very kind, serious, responsible and helpful. They gave us their cell numbers in order to contact them in case of any issue, we contacted Pierre once a Sunday night (because of a problem that was our fault) and his response was immediate and very helpful.
All in the flat is as described by Adrien, clean, bright, all functional, the 5 of us slept very well there, it has a great kitchen, fridge with freezer, very hot water (you would appreciate it a lot during french winter) and great heaters. The sightsee from the living room and bedrooms is amazing, you can see the Eiffel Tower from there, and is incredible by night!!
The neighborhood is lovely, 2 blocks from the Triumph Arc and the great Champs Élysées Av, very quite as well, and with a Monoprix and pharmacy just around the corner.
I would like to add that since the very first day we contacted Adrien, he showed very serious, kind, comprehensive and he listened to us and did his best to help us with a little difficult trip logistics we had until he resolved it for us. Thanks to Adrien, Paul and Pierre to help my family and me to have had a wonderful vacations in Paris!! Thank you for the beers and the french wine as well, great details! No doubt we would return to Adrien's flat next time we visit Paris.
