I recommend Giota's cute house. We were well received. She seems to be a dynamic and friendly woman like every people we met in Santorini. People are really helpfull and Lovely. You will find everything you need on this apartment and around. Fira is perfect for a stay in Santorini. Central, with local buses, Shops and wonderful view on the Caldera.
Giota will provide you little advices before your arrival and will answer all your questions So you can travel easy. Thank you Giota ! We spend beautiful days in this wonderful island
