I stayed several times at the Lippischer Hof due to it's convenient, central location within downtown. You can literally reach all restaurant and bars by foot, which is very nice if you want to enjoy the German biers. Rooms are clean, but some are rather small. Breakfast is very comprehensive and offers a wide variety. Free wireless internet access. Parking is indeed a hassle, but there are parking lots close by which are free during the night or over the weekend.
