We stayed in Ersi villas for 7 nights and found everything wonderful.
The location is perfect to reach the beautiful center of Fira and Firostefani in a few minutes (by walking) and also strategic to reach every single beach by driving (we rented a Quad bike for the whole week).
For only 5 Euros per person it is possible to have breakfast near the pool at Ersi villas. The room was big enough for two people. Every day it was cleaned and new towels were provided.
Elias is a gorgeous person, very helpful and available for gathering information about the whole island. He also gave us a lift from and to the airport.
Of course we will visit Santorini again because we liked this destination a lot and we will not hesitate to stay in Ersi villas again!
