We have stayed here with 12 people for 6 nights and it was an amazing time. The apartment is really spacious, clean and easy to reach because of its central location. The check-in times are flexible and the possibility to store our luggage before the check-in and after the check-out was really convenient. In the kitchen there is everything you need but cooking for big groups can be quite a challenge on the electrical cooking plate. During the night there is a night guard to keep an eye on things who is very sympathetic and always prepared to help us. When three of us came back from a club somewhere after midnight whithout a key, the guard was there to help us get into our apartment. Taken everything into account we would really recommend this apartment for big groups (if you are responsible enough to be quiet during the night).
