I can't understand people who say that this is better than Waldorf-Astoria Berlin. In fact this worst Hilton hotel where I have ever been. The Executive room that I had booked (6022) is equal to most standard rooms and even that is giving too much credit for it. I also had issues with low water pressure on shower and bed was bit wobbly.
Executive lounge offering is also nothing to write home about although I wasn't there for evening offering last stay. Will check that today as I unfortunately have another stay booked.
Should have booked these stays other way around with two W-A and one Hilton.
If you want to book Hilton in Berlin and care for room, go for W-A. Even their standard room is twice the size and much better furnished.
