There was a minor misunderstanding at the beginning but the host was very quick to reply and make things right. I’ve never had such good communications with an AirBnB host. They were quick to respond each time...within a couple minutes each time. The location was excellent, just 1 min walk to the RER-A station and there are cafés and food on every corner. The unit was extremely clean and recently renovated. Check-in and check-out was effortless. Great place and great host.
