We had a great time at Alexandre's apartment, and with 3 young kids, one of which is a baby, it's not an easy task.
When we left, the kids asked when can we come back, they had so much fun!
First of all, the location is fantastic - right next to a metro station, everything you need and want in Paris within 5 minutes of walking including Rue Montorgueil which is just awesome.
We found the apartment spacious and true to the photos we saw on the site and had ample of space for everyone.
Alex was really great and spent quite some time to answer all of our questions, so we had an insider view on Paris right from the start - for me it's invaluable.
There were a couple of downsides, both aren't critical:
Some furniture was falling apart (drawers, floor).
Elevator was really small (no, really really small) and started on the first floor.
