Eleftheria's place is absolutely amazing - a very spacious and bright house, with a fully equipped kitchen and amenities, very close to the main bus station and city centre.
We didn't lack for anything during our stay and at check-in Eleftheria gave us some very precious information with regards to places to visit, restaurants and foods to eat, and she even helped us with transfers from and to the airport & port. We were really impressed with the cleanliness of the place and even though it's situated right off the street, we were never bothered by the noise outside (because you can't hear it). There are AC units throughout the house but we very seldom had to turn them on.
We have made it a personal goal to try and get back to Santorini regularly and this is definitely the place we'd love to stay again and again.
