This is a good, clean functional hotel, with a modern design, at a reasonable price (for Austria at least).
It's a little away from the Krems centre - it's on the edge of the Stein area - but this is still only a 10-minute walk away from the main drag.
We used it as a base to explore the Wachau and Danube. It has a bike station on the hotel where cycles can be hired for the day.
All-in-all I'd recommend it.
