We had a lovely time in Manolis's place. Kalamaki is a small, peaceful and relaxed village, and the house is located in a perfect position right in front of the sea and next to nice tavernas. The sea is as close as can be, just walk out and you're on the beach!
The house is very elegant and modern, we had a nice time just staying in when the heat was too much for us, and in the nights the double-pane windows ensured we got a quiet rest.
Highly recommended :)
