Irini's Sunhaus is great. Traditional, yet modern, full in nice details, yet very minimal. We felt very good, we were 2 adults and 2 small kids, we found the space welcoming and enough for us. The kitchen is very much helpful and the separate bedrooms us well, with separate exits. Irini and her husband are nice, patient and very well documented hosts, we also had the chance to meet their kid, which was extraordinarily convenient toys-wise for our daughters, we might stay there again if we were to visit Santorini one more time. The beach just on the other side was another big hit. Perissa is also a very good place to stay and plan your trip around it.
