We had an enjoyable stay at Irene's place. The location is great - right next to the beach, walking distance to Perissa, a very short walk to restaurants, grocery stores and a bus stop that makes the northern part of the island easily accessible. The room was very basic, but clean. One thing that was a bit less than ideal was the bathroom, which was very small (and the shower was very tiny). Overall, however, good value for the price.
I would like to add that Irene was a great host - she gave us a lot of details about the island and its history and even cleaned our room while we stayed there!
