The apartment itself was clean and all we needed. Plenty of beds for everyone and the washing machine & dryer were handy to have. The area was easily accessible via the metro, and only a short walk from the nearest station. It felt like a safe area, but it was a bit "adult" if you have young kids to think about.
Staff were usually very helpful, and even though they forgot the high chair and cot initially, the cot was sorted within a few hours and a high chair the next day.
We did have some problems getting our hire car out of the secure parking area on the weekend, which took a few hours to sort out. We recommend that you make sure you have the badge, swipe & code for the security gates upon arrival! Overall we enjoyed our stay despite the hiccups mentioned above.
