Park Inn by Radisson Berlin Alexanderplatz

Rooms are small and basic for a 4-star. The bathroom has glass walls with no real privacy — the toilet and shower are open to the room. The shower door leaks water onto the floor. Beds get mixed marks: some find them comfy, others say the mattress is too hard and the pillows are flat. Upper floors have great city views. Noise from the corridor and ventilation is a recurring complaint.
