Casa Sofia is a stunningly located apartment, with excellent views of the volcano island. Everything was well organized, and we were picked up at the port at Thira with a Pre-booked taxi with the help of Maria, and then met at the bus station at Oia to walk down to the apartment. Maria also helped us with arranging island excursion tickets. The apartment has ample space, beds and amenities, with an outdoor bathroom & toilet. The view is beautiful on the terrace, and is only a short walk to the main streets to the shops, restaurants, and viewpoints. It is about a 10 minute walk to the castle ruins to see the sunset. Would definitely recommend!
