My wife and I will be visiting Santorini in this coming May. We are considering staying at Villa Lukas in Imerovigli. Can someone please advise how long of a walk it would be if we are considering going into Fira for lunch and dinner or taking in the nightlife? Will we need to take a taxi each time? We are considering renting a scooter or ATV however, that will probably only be on days we are travelling around the island.
