The days that we had in Iro's apartment were like living in paradise except we were alive and not dead :) The apartment is wonderful, the two terrasses allow us to enjoy during the morning of nice temperatures and during the evening of a cool spot to relax us after a day spent at beach. Inside we had all we needed nothing more nothing less, just perfect.
Regarding Iro, she is the perfect host, she welcomed us at the port and helped us to go to the apartment when we arrived. One morning she came to bring us fresh fruits from her garden and another morning she brought some delicious sweets that she cooked. And when we left the island, Iro drove us to the port and offered us a coffee.
If Kythnos was a really nice island, it was perfect due to this apartment and Iro's attentions and we definitly come back one day !
