Villa Hilal is a lovely property sitting some 2km above Kalkan with great views of the bay. Mike the owner was very helpful and responsive, Umit the local property manager met us at the villa at 1am following our late flight. There was a generous welcome pack of food left for us, the villa is as described in VRBO and is very well equipped both inside and out.
We loved Kalkan , the old part is lovely with many shops and restaurants. The villa is at the top of a steep hill so we tended to walk down into Kalkan and get a taxi back (£3) if we weren't feeling energetic.
There is quite a lot to do in the area, our favourite things were kayaking around the sunken city/Kekova, walking up the Saklikent gorge , Patara Beach ( part of a nature reserve ) and eating at the restaurants in Kalkan ( 'Akin' was one we particularly liked). This was our first time in Turkey and we found the Turkish to be very friendly and helpful.
Couple of things worth noting, taxis aren't so expensive and are plentiful, so depending on your needs and plans you may want to use taxis as required vs hire a car. E.g. the 1.75 hr taxi tfr from Dalaman airport to the villa was £55. Also turn off your roaming on your mobile device before entering Turkish airspace as data and call costs are very high - buying a Turkish SIM card is apparently a cheap solution if you want to stray from the wifi.
Overall a great holiday and we hope to be back.
