This hotel has the best breakfast of any hotel we've stayed at EVER! The statement listed the price as 5 Euros per person (although it was included within the per night price). Variety, quality, all excellent...worth MUCH more than 5 Euros.
Beyond the breakfast, the room was clean, airy, bright, and well appointed. Our only concern was that on arrival, we were told we'd need to stay in a building 1 and 1/2 blocks from the actual hotel. This ended up being okay, but we were a little surprised. Being actually in the hotel would have been better...all the same, this place deserves a 5 rating.
Also, it's just a short walk from the 707 strassenbahn from the railroad station, and only a little farther to the 721 bus which goes directly to the airport. Great connections. Finally, it's just a short walk to the Altstadt.
If ever we're in Duessedorf again, we are staying at the Hotel Berial.
