Great place. For payment via the indicated app 'Gomarina' you do need a credit card. Sanitary building perfectly clean and fairly new or well maintained. Just before you reach the port, there is a sign on the left to a motorhome. This is another little further on. We liked the port better. Is also slightly cheaper: 130 DKK and 2x 5 DKK for shower. Need two 5-crown pieces!
