We pay (May 2023) €28.80 per night incl. electricity. It's a small camper place at a hotel. Of the 5 places, only 3 are actually available for campers (there is also a swimming pool and a tipi tent). Excellent sanitary facilities. Emptying the toilet and discharging gray water are actually not possible, but if you lift a manhole cover in the driving path, you can at least empty the cassette toilet. From the campsite you can easily cycle to Quedlinburg.
