Irini is a delightful host--warm, funny, generous, communicative. She even brought me some of her homemade spoon sweets with yogurt, which is about the most delicious thing ever.
The little rooftop house felt like being in a boat--lots of big breezy windows and a view of the beach, the mountains, and half of the city. Great location for walking anywhere in old town, to the port, or to the beach. As other guests have said, be prepared to eat simply (or just walk to the many bakeries & restaurants) as there is no means to cook; there's an electric kettle, a refrigerator, and some basic dishes only. This was no problem for me, and worked out just fine.
Irini also has a taxi and arranged rides for me to and from the airport--so helpful, since the buses run infrequently in the off-season.
I would definitely stay at Irini's sweet little house again.
