The Gasthof zur Sonne is an excellent Gasthof and Restaurant managed by Klaus Sackenreuther and family. The property is located in a pedestrian only [car free] Fußgängerzone only 30 yards from the Rathaus town square and 75 yards to the main Käthe Wohlfahrt store. However, it is too far to walk from the Bahnhof but the taxi fare was only 4 €.
Our 3-day visit was during the second weekend of the Christmas Markt. Klaus greeted us and the entire staff was overwhelmly friendly and spoke very good English. You will find a reserved table for Frühstück, which consisted of the basic breads, cold cut meats, cheeses, yogurt and cereal. There was a nice selection of typical German food and wine from the restaurant menu.
There is a mini-Mart across the street and a larger market with beer a short walk away. Our room, Zimmer #1, did not have a minibar but a window ledge always works well for us.
We booked our stay directly with Klaus and his reply to our e-mails was always prompt. TA does not allow me to post their www or e-mail address but you can look it up. Their location and price [73 €] were by far superior to any of the other hotels that I had contacted.
