The esiest way to move around the island is by renting a car at the airport. Still, if you are not renting it you may take the express bus line number 91 or 90 or the regular line 01. The bus stop is just outside the airport and it'll drops you a few steps from the apartment.

Once you are at the town you could go anywhere by foot. if you decide to explore further there is a bike rental shop close to the apartment.
