Staying at Gaesthaus am Klosterhof (and visiting Rotenburg ob der Tauber in general) was one of the top highlights of my trip to Germany. Mario and Hanne were exceptional in their service and have made a wonderful retreat and a chance for you to relax a little.
We stayed on the top floor of the guesthouse in what turned out to be a suite (foyer, bedroom, sitting room, bathroom, kitchenette). It also had two televisions (no english language programming). And we stayed (two people for two nights) for a sum that was unbelievably low.
The guesthouse is located across the street from Mario and Hanne's hotel and restaurant and I strongly recommend you eat there at least once. Fried camembert, homemade potato soup, a plate piled high of sausages and a couple of big beers make the evening very enjoyable.
Am I heaping on the praise? Sorry. It's just very excellent and I would go back at the drop of a hat.
