You paid 60 euro!? That's bloody good. Sorry to resurrect for no apparent reason other than that we stayed there for a family short break a few weeks ago. Combination of paid and points. Pleasantly surprised with it although I squeezed them to get free breakfast being spire. If I was paying for breakfast for the 5 of us it might have been a different matter.
As a side note, first time for us visiting Berlin. Great city but the cost of visiting the museums is really expensive. We bought the discount cards but even then it's high. Didn't go to the spy museum as it would have cost us 80 euros to get in.
