We stayed in another of Stavros' apartments, which was really nice (in between Irene 1 and Irene 2, about 15 minute walk from the ferry terminal). Suitable for 2 people, I wouldn't advise to have 4 (you could, at a push, have a 3rd person sleep on the sofa). The apartment is only a few minutes walk (5-10) to town and to the beach. The only minor point was the weak internet. We used our 4G phones most of the time. Stavros is quick to respond to questions.
