The flat is very nice for families with children and it is within walking distance to the Louvre and Tuilleries. It is also very convenient for transportation. The closest station, Chatelet, goes straight to the airport and connects to the main lines. The check-in and check-out went smoothly and communication before we arrived was good.
The central heating was still out of order but there were electric heaters for each room so we had no problems with the cold. The equipped kitchen and the washing machine were very useful.
The flat is spacious and the children had enough room to play around. We did miss having curtains on the living room. The high windows are very nice but not very private. And with only one toilet for 5 people, some organization is necessary.
Overall, the flat was just what we needed and we would not hesitate to come back.
