Our party of 6 enjoyed our stay at Schloss Mörlbach, although we were startled to discover that it was something between a hostel and a hotel, which was disclosed after the booking but not in the listing. For instance, our listing was for a 3 bedroom apartment with kitchen, but it turned out to be 3 bedrooms at the end of a hall with two private baths, one shared with the entire building, and a kitchen shared with all the rooms at that side of the hall. This wasn't necessarily bad or good, it was simply a surprise, especially at the price point (which was the same as area hotels).
But the rooms were comfortable and clean, the fresh milk was delicious, and the building was surprising and unique, a nice memorable stay. I wished that we had a private area for our large group to call our own, but other than that, very nice.
