The appartment is really big and it was perfect for our big family (8 people). Getting the key was easy and Eugen was kind enough to let us in a bit earlier on the arrival day, which made a big difference for us. We were also able to cook and had a lot of space to enjoy our stay. It was also good that there were 3 toilets and 2 showers, especially with so many people in the house. The house is also near the central bus and U-Bahn stations which nade it easy to get around the city.
In total, we had a really nice stay and I would definetily recommend it.
