The location is awesome! It's also great that you can book a parking space, even though one needs good skills to park there :) The kitchen of the bigger living flat is really nice! We enjoyed our breakfasts there every morning.
We didn't know that they are actually 2 separated flats instead of a huge one that got 4 rooms, which made us slightly disappointment. Some glass-door-bathrooms are not really nice, as the water can flood out of the bathroom easily, and the sound can travel quite far.
All in all, it's a great place for big groups!
