I had been told that there tends to be amazingly long queues at check-in and check-out, but we arrived late and left early, and everything went smoothly. We had a standard double room, which was quite small but tastefully decorated in cream / dark brown colours. Our room had a comfy double bed, two chairs and a small table / work desk, a nice little tv and a minibar - and a rather odd bathroom set-up.
I would recommend only to stay at Park Inn Berlin Alexanderplatz with people you're fairly good friends with - as the bathroom doesn't really offer much privacy. :-P The tiny toilet cubicle, shower and sink are all separate - and the shower and sink has got glass walls. (!) There's a shower curtain, but it was too small to cover the entire shower area - so you might inadvertently be offering your room-mate a bit of a striptease. :-P
WiFi is available, and costs 2 euro for 15 minutes, 8 euro for 1 hour, 14 for 3 hours and 18 for 24 hours.
We paid ca 80 euro / night, and found this to be good value for money. Our room rate did not include breakfast (which was available at an additional 16 euro per person - we chose to have breakfast at one of the many cafes nearby instead. ;o)
For good views, ask for a room on one of the highest floors, facing the TV tower.
