I had a very pleasant three-night stay here in room 14 on the third floor overlooking the Prinzengracht. Everyone at the hotel was very kind, gracious, welcoming and warm. The room was compact but spotless, with an excellent shower, dual sinks, safe, small mini-bar, and comfy king size bed. WiFi was fast and reliable--there is no dinner restaurant, only breakfast, which I didn't elect to have.
Overall excellent location and a stunning view of the canal if you opt for one of those rooms.
