We had a very nice stay in Laurence's flat, close to the Paris Expo. I would give 5 stars, except for a few small things.
First, the positive: the place was lovely, with a fine view and comfortable amenities. Laurence was very responsive and helpful. We were very satisfied overall.
However, a couple of minor negatives. First, Laurence asked for proof of liability insurance, which no AirBnB host has ever requested from me before. Second, we rented the place with the expectation of using the couch as another bed, which we learned only afterwords was forbidden. Third, the host sent multiple messages afterword asking for a review, when one reminder would have been sufficient.
Other than these relatively small objections, though, a good choice.
