The apartment is everything you could ask for. It's literally across the beach with a dream view from the balcony. The apartment itself is very clean and basic and has everything you need.
Unfortunately we didn't had the chance to meet Ioanna herself, but her family welcomed us with open arms. They own a kiosk across the street of the apartment on the beach and are always more than happy to help you out.
Stegna is such a special place to stay. It's not too big and crowded with tourists and has a lot of nice tavernas/restaurants (be sure to have some seafood at Kozas, it's delicious). Everybody in this little town is so welcoming and kind, we almost couldn't believe it. The sea is perfect for swimming, snorkeling and watersports with its cristal clear water.
We rented a car to drive around the island which is perfect. There is parking space in front and next to the apartment.
In short: Great apartment, wonderful little seaside town and very warm and welcoming people. We will definitely recommend the place and will come back if we have the chance.
