If you want to stay in Perissa, then choose Ritsa and this listing! First off , Ritsa is an amazing host and is so helpful in booking anything you need , or giving you ideas on what to do. Our time here was flawless! If you are looking to stay in the area, do not hesitate and just book here! Also, the morning breakfast is an amazing way to start your day.
I would recommend renting a vehicle though, as the drive to Fira is ~20min and Oia is ~40min. Although those seem far, the drive is extremely pleasant and beautiful!
