We loved staying in Villa Cosmakis.
George was so nice and responsive, and his parents were very welcoming. George's mom even surprised us one evening with wonderful homemade gemista!
The location was just what we wanted - quiet, very close (by car) to the beaches, with a bunch of hiking trails in the proximity, and beautiful villages to visit.
Two things to note are that the beds are in the galleries, not in actual closed-wall rooms, and that there are in fact 2 units - if you need the 2 bathrooms/4 beds then you need to inquire about both. We were 4 people and used one unit - which had 3 beds and a single bathroom.
