We stayed at the appartment for 5 days and it was great.
Excellent location - 1 min. ealk to the U Bhan, 10 min walk to Alexanderplatz and the train station, in a walking distance from the Mesuem Island and the Mitte cental.
The place is well equipet, new towels & bed linen, all you need in the kitchen and the shower is great.
We highly recommend the place.
