I stayed here for one night whilst visiting Passau.
The hotel is in the old town, right next to the Danube and close to the cathedral.
The room was very comfortable with a nice seating area by the window. There was a large HD television on the wall with plenty of channels to choose from. Wi-Fi was free and had a very strong signal everywhere in the hotel.
Breakfast was good, with a large selection of breads, cheeses, cereals and some hot food too. In summer you can take it on a terrace overlooking the river.
I booked directly with the hotel and paid 45 EUR for a single room (actually got a twin) which was excellent value for money for a hotel of this standard.
I would definitely stay here again.More
