Hotel receptionist was extremely rude. Declined to help with taxi reservations as they required certain steps because it was a business trip. Slammed phone on the counter and said book it yourself I'm busy. Complained 2 minutes later while I was on the phone doing the booking that I should leave the phone free. Buffet was poor and did not serve cold cuts other than pork.
Very bad experience, do not recommend. There are lots of other hotels in Berlin.
