I stayed at the Dormero for a week of business nearby. I was in the White Wing. The room was completely fine. It was a bit sterile, but that could be the Scandinavian influence. I liked the weird lighting scheme. (You can set the lights for your mood.)
The place was clean and quiet. I don't think I heard anything from outside the room while I was there. The staff were very helpful, scanning a couple of things and then emailing them to me. The place is ideally located with restaurants in the hotel (they were OK) and across the street in a complex there. It is nearby to Kelley Barracks. Also, all of the movies and the snacks/drinks in thee mini-bar were complimentary. Not sure if that is normal or just because I'm so special. :)
My two complaints would be 1) even though it wasn't staggeringly hot, but the A/C struggled a bit to keep the place as cool as I would have liked and 2) the really nice SchwabenQuelle sauna area is not complimentary from the hotel. So, they really didn't have a sauna to use for the guest. But overall, I liked it quite a bit and would highly recommend it for travelers.
