Hotel Lessing is in a good location close to a train station. The staff were very welcoming and friendly and the room was spacious and comfortable. We were given free local transport tickets by the hotel but only used them for the train back to the airport (about a 15 minute ride) as we walked everywhere else. Konigsalle is about a 15 minute walk and then another 5 or so to the old town. New year's Eve was amazing with fireworks being let off on every street corner. They obviously aren't handicapped by the same health and safety requirements that we are here!
We had breakfast once during our stay and although the choice of food was amazingly good, we thought it was expensive at 12 Euros each (especially as my wife only wanted some toast and coffee). The following day we found a bakery cafe 5 minutes walk away that did great sandwiches, coffee and cakes for a total of about 4 Euros each.
We have no hesitation in recommending the hotel to others.
