The hotel name is now NH Parkhotel Deggendorf. I agree with the previous review. I was in Room 122. It was relatively large by European standards, as was the bathroom. It was clean and reasonably modernized, with wireless Internet access in the room (provided by swisscom eurospot for 10-15 euros; a bit expensive). At the end of the road (a few doors down) is the Ruderhaus, which is a great restaurant and beer garden right on the Danube. I went to a wedding reception there, and I really liked it. The staff were nice and helpful. Parking was easy; there is a small parking lot essentially right in front of the hotel lobby. The hotel decor is a bit bland except for the lobby, but it was plain, not ugly.

The hotel is outside the historic city center, but it is a short walk. Even though it is on a road that only leads to the Danube river, and next to the city hall and city hall park, there was an amazing amount of traffic and noise. Of course it didn't help that our room was above the main entrance, and with no air conditioning, an open window and several busses full of tourists from Switzerland and the Netherlands arriving late at night ... you can imagine. The room was of a decent size, bathroom ok, everything clean.
Very nice breakfast with good choice of everything. Jacuzzi and sauna which we didn't try. Everything ok, but lacking character, though the large and open hall with a huge modern painting and the adjacent bar with chimney were nice.
