We have been in contact with several co-hosts of Kostas and they were all super friendly and helpful. We were traveling in a difficult period, because the rules and restrictions for flying in Greece changed daily, during our stay! Without the help of the hosts we would have surely stranded!
Apart from this the apartment was great, the showers also really good and lets not forget the jacuzzi on the roof. We were so lucky that when we enjoyed it around 23.30 a fireworks show started above our heads. Really special!! A definite recommendation!
