Thanks to Emmanuel & Yannis for the great communication, exact information and swift replies.
I would highlight the outstandingly high support of the local host: Maria. She was always available and supportive.
We chose the apartment on the ground floor because of the garden connection which used by the kids every day. Under the shady arbour of grapes, you could sit in the swaying wind all day, it was never warm, as well as the climate of the apartment was excellent despite the great heat it was enough to open the windows during the day.
The apartment was spacious with a good layout enough for a family (5 members), the kitchen was well equipped, beds were large and comfortable, and the baths were modern and beautiful, the washing machine, dishwasher and huge fridge were a big help to us.
Perfect location 4 sandy beaches were less than 10 minutes from the house, wasn't easy to figure out which one to go to. 2 huge supermarkets within 5 minutes by walk, as 2 nice restaurants and 2 car rental agencies too.
We strongly recommend this apartment.
