"Nice view, but no wifi"
One bad thing about this hotel is no free wifi provided. It needs a charge of EUR 9.9 for 24-hour wifi.
And you could not detect the "charged" wifi in your room sometimes. Need to browse the net in lobby.
Otherwise, excellent location, with only 2 minutes walk from Alexanderplatz station. Bus station (No. 100, 200, TXL) is just outside the hotel.
Good view from room. You could see the TV tower, Red City Hall, and Berlin Cathedral from your room. Nice environment indeed.
Breakfast was not included, however.
