Everything you would expect from a small city centre hotel was to be found. The initial welcome and subsequent customer service were excellent. We arrived well before the official check-in time but rooms were ready and we were given immediate access.
The room was spacious, well maintained, extremely clean and comfortable with a very limited free soft drink/beer minibar (it would have been nice to have a tea/coffe facility in the room as well) .
Breakfast choice and quality was very good.
WiFi in room was fast and worked well.
The location of the hotel was ideal -- it was an easy walk to the Altstadt, the river, the designer shopping area, and the underground rail system.
I would consider the Hotel Favor excellent value for money and would definitely consider staying here again if I were to return to Dusseldorf.
