The property was in an excellent location for really anything you would want. It can't be more central. The Hotel itself was great, the staff were very accommodating and spoke excellent English which was helpful to us.
Cleanliness would be a 10 for me, the room was so spacious it felt like a suite and not a regular room and the amenities were brilliant too.
If you're visiting Dusseldorf, I would recommend this hotel to anyone.
