Well, great location and connections to everything in Berlin, the rest is typical ibis with a couple nice of exceptions:
- Great view over city (from Potsdamer platz to Alexander platz) if you are on high enough floor.
- Absolutely wonderfully, modern designed lobby with projection. Probably the best ibis lobby I've seen yet.
Oh, one more thing: shower would take some time (5 min or so) to pick up hot water. So my conservation nature was a bit disappointed to waste water for this matter.
- Free Wifi
