We (couple) had a nice stay in this well situated flat in Marais. Although we did not meet our hosts personally, everything was well organized. Communcation via Mail and telephone was easy. Alexandra even booked us a table at a lovely restaurant (Chez Janou) for New Years eve. The sleeping room is small, but because the family was on vacation we could use the whole flat for our own and shared the kitchen-living room only with their two friendly cats.
Maybe because this was our first time with Airbnb it was not transparent for us that our hosts charge 16€ more per night because it was holiday/New Years and we had the apt to ourselves. This was the only and very little disappointment.
