The site is a house garden with obviously small sanitary facilities. When I saw it, I thought it would cost 10 euros. But no, the owner wanted 30 euros for 1 person with a car roof tent without electricity. Greed is not a nice trait. Now I am 5 km further west on the same river and pay less than half, with bread roll service. The last few nights I was in Cologne at the private Rheincamping with a great sanitary building for 19.50
