The hotel was in a very central location, with easy access to the airport and only a few minutes away from Alexanderplatz station. East walk to museum island too. I was upgraded to a room with a view of the Berlin TV tower which was nice (sadly couldn’t see anything as it was very foggy but that is not the hotel’s fault). Staff were all friendly.
The area late at night is not the best, with lots of rough sleepers so something to be aware of. I didn’t try the breakfast as, other than boiled eggs, it didn’t offer any hot food, it was mainly continental (pastries etc). I found the bed and pillows a bit hard.
