We stayed one night to catch an early flight out of Dusseldorf the next morning. The room and bathroom were in excellent shape. The pillows were a bit too soft, but the bed was otherwise very comfortable. Shampoo, body lotion, and body wash were plentiful in the bath.
The Internet was spotty, however. The staff seems to be aware and said they reported it to Telekom.
When getting to the airport, you cannot choose a better location. You can take bus 760 from in front of the hotel. The airport is literally 5 minutes on the bus. Two stops. Much easier than taking the S Bahn.
