Unfortunately, we had check-in and check-out issues that compromised our stay. If we didn't have a person living in Paris who helped us a lot, the problem would be even greater. Upon arrival, in addition to the keys being far from the apartment, the location informed to retrieve them was wrong. Communication was difficult and we were on the street waiting for a long time, minimized by a friend who lived in Paris. The same thing on the way out, only worse, there was no one or place to receive them and once again, a friend helped to try to deliver, since we had an early train scheduled. A pity, beautiful apartment, but these issues are very serious!
