If you stand outside the building, you'd never guess such a wonderfully unique Boutique hotel is hidden behind. Our room was huge with the biggest bed I've ever slept in, armchairs, a big TV, dining area and more. The bathroom was small but clean and the location very close to the city centre, Tonhalle, Rhine and especially the train station is great.
It's at a crossing, so a little noisy, but the windows shield the noise off quite well.
