I was lucky. I had to travel to Berlin on these dates and didn't realize if there was a Berlin Marathon on the same date. All hotels near the train station were fully booked, and miraculously, I got this corner room with a two-window view, including the TV tower. I can see the hotel is one of the historical buildings (saw the picture in the DDR museum 😁), though it was refurbished well. The breakfast area was packed with all the runners, but just enjoy the moment :) I will definitely come back to Park Inn if I have the chance to visit Berlin again.

The hotel is right outside the Berlin Main Train station and it is very close to all random checks to this hotel-main transaction. The hotel has easy access to airports (it is so cheap from Tegel (TXL) airport). Overall the room was clean (even though the toilet bowl would need to be cleaned more). The hotel has kitchen sharing facility and the receptions were helpful. I will definitely stay again.

Pros: clean room, comfortable bed, fast check in, nice receptionist, near Berlin hbf, near bus halte, near tram halte, near you bahn halte, shower with different area so bathroom is still dry, beautiful scenery outside, easy to go to airport with bus, fast free WiFi. Cons: -
