These distances are exact, but are based on a straight line from point to point. Actual walking distances will be slightly longer.
Later in August 2019, ok, but not that nice. No toilet seats, no cooking allowed and cloths drying racks are in the humid bathroom where they dry very slowly. Can get boat tickets from two different companies leaving at very different times.
as of August 2019 price is 7€. Alb is very nice.
