We stayed in Stylianos and Radka's house in the Chora on Ios. The house was delightful and in the traditional Cycladic style but nonetheless with all modern conveniences. A lovely breakfast/ eating area and garden added to the appeal of the house. The Chora is a beautiful part of the Island, just be prepared for a few stairs. Stylianos and Radka were great hosts and answered a bunch of questions that we had. A detailed list of suggestions and recommendations from them really helped us enjoy our stay.
Ios is a beautiful island with great beaches and an "active" nightlife if you are inclined. Our 18-year-old daughter and friend came along with us and had a great time partaking in the nightlife whereas we enjoyed the beaches.
