Muy husband and I had a great stay ay Volker's apartament, it is situated very close to the city's top sights and the bikes are the best way to explore the surroundings. The bed is ver comfortable and there is a big window that makes the room very bright. What I liked the most was the so easy and confortable key pick up, even though we didn't met zvolker he was very nice to us all he time, in our last day he let us stay as long as we wanted and refused to accept any money
