We had a wonderful stay in the appartement with our 2 children of 12 and 15. It has everything you need and is located near the metrostation and large supermarket. The area is very lively but the appartement is in a courtyard so it's quiet and we loved eating our breakfast on our own terrace. In the evening this courtyard closes with a gate where for you need a special key (make sure you receive this otherwise you cannot get to your appartement) and this feels very safe. The contact with the agency was great, Christopher picked us up at the metrostation to bring us to the appartement and made us feel very welcome and there were breakfast supplies for the first morning. If we had questions or problems we could call him and he was very friendly and helpful.
We loved our stay and would certainly come back!
