We had a great stay at Manon and her boyfriend's place. We felt welcome, as they had bought breakfast for us (we arrived late). Also they were very flexible when it came to both our arrival- and departuretime!
The neighbourhood was a little more suburb than we expected (with a lot of hookers close by), but it was all right - we felt safe. Also, the carpenter began working very loud in the stairway everyday by the time we got home at 5 PM. Guess we were just a little unlucky!
We thought the apartment could be slightly more clean as well.
But from an overall perspective we had a nice experience with our temporary home in Paris!
