The ground floor flat was everything we hoped for. We were only two people but there would be plenty of room for 4 - the flat is very spacious. Particularly lovely was the long patio with a view of the White Mountains and a choice of lounging in the shade or the sun - also a great place to eat meals.
Stelios (George's father) met us on arrival and made us very welcome. He had provided a very generous welcome pack of goodies including his own wine and olive oil and a good starter pack of provisions.
Aptera is a very mellow and quiet village with three or four good tavernas where you can eat well and cheaply (we ate at both Cretan Corner and Ta Aptera and can recommend both). There are good beaches a short drive away (having a car is pretty essential if you want to explore). We mainly visited a beach just to the west of Kalyves (turning left a little before the filling station on the road from Kalami signposted GK beach cafe/restaurant, which was actually a pleasant place for a drink or snack). Other, more picturesque, beaches were at Falassarna and Stavros but there is plenty of choice.
There are good food shops in Kalyves (great fruit and veg and a good butcher).
We had a really wonderful and relaxed holiday and really appreciated the care taken by George and his father to make us comfortable.
