Arnaud have been a very kind and prompt guest. He responded to all our requests and trips changes (we had quite a few). But it was never a problem and he solved them all. The information in order to get to the flat and on how to check-in/check-out were very clear.
The flat is perfectly suited for 4 people (but we stayed in 6 without problems) and is very nice, clean, well-curated and has all it takes to get fast to the metro and visit Paris.
Personally, we enjoyed our time spent in Paris! We'll definitely suggest Arnaud and his flat!
