Park Inn by Radisson Berlin Alexanderplatz
I was lucky. I have to travel to Berlin on these dates and didn't aware if there was Berlin Marathon on the same date. All hotels near train station was all fully booked and miraculously I got this corner room with 2 window view, including the TV tower. I can see the hotel is one of the historical building (saw the picture in DDR museum 😁) though it refurbished well. The breakfast area were pack with all the runners, but just enjoy the moment:) Will definitely comeback to Park Inn if I'm having the chance to visit Berlin again.
