We had spent 3 nights in the flat, 2 adults and 2 kids. The flat is spacey and bright, 2 bathrooms are perfect for a bigger family. There was just two minor downsides, our baby stroller didn't fit (width 60cm won't fit) in either of both elevators, luckily for us there is an option to remove on wheel on stroller and then it fit like a glove. Second downside is that the flat is suited above a rush highway with cars passing almost 24/7 so if you want to sleep with windows open bring up your earplugs. On the other hand, I really appreciate the host provided us baby cot and baby chair for feeding. There was also infant water waiting for us when we arrived.
In the end I recommend this flat its beautiful, big and really nice. We never met the host, keys were hidden is safety lock.
