Gasparis has been a really perfect host ! He came take me near a hotel (I couldnt find the flat immediatly by myself...) and during all the vacation him and his wonferful family have been ready to support me in each request I had (from turistic informations to taxi booking and more !).
The flat is exactly how it looks like in photos: it s cute and big enough for two person. In the price it's also included some houseworks as floor washing, towels and sheets change !
From the flat u can reach the seaside (perivolos) on foot, it's just 3 minutes...! In perivolos u'll find the best beaches of santorini and a lot of cafès, pubs and restaurants; so if u are planning to have just beach and relax u dont need a scooter or a car. If u want reach fira or oia a bus stop it's near and it's quite easy reach these towns just with public transport.
otherwise if u would like to rent a vehicle i suggest dont take a car because it will be difficoult find a park. On the island it's also popular rent a quad but i think that a scooter will be the best compromise !
from perivolos to fira, by scooter, it's about 20 minutes but be aware that the road it s full of twists and u will drive up and down hills...
