Great business hotel in Berlin
This is a large business-oriented hotel in the heart of western Berlin, rich with amenities and services (but lacking in Berlin charm, if that's what you're going for.)
My room was very nicely appointed with a comfortable bed, contemporary and interesting furniture and decor, and a luxurious bathroom. Internet access (wired) was free and extremely fast and reliable. The front desk staff was efficient, professional and friendly.
The only downsides was that the bar, while nice enough for a drink, didn't have a lot of character or activity. And the workout room only had a few treadmills and stationary bikes - no weights (which was surprising).
I'd very much recommend it to any business traveler.
