I had a pleasant stay at Giannis house. Thanks for your warm hospitality. I can defenitely recommend Giannis house. The jacuzi at the rooftop was really nice. In the house you find everything you need. There is also some beach equipment available (umbrella ect.)
Better you rent a car to dicover the island. The bus stop is ca 15- 20 min walk away. Time from Heraklion with bus is ca 70-80 min and costs EUR 6,50 / each way. (departs 1 x / hrs). Costs with taxi ca EUR 60,00/ each way (ca 30 min). I also chose the bus to get to Retymno for EUR 3,50 which is only 40 min away. Thanks for all. Nadine
