We enjoyed our stay at Altea, as it was only a 5 minute walk to the shops and views in Fira. The unit was cleaned every day and had plenty of space inside. The staff was helpful and kind from start to finish. Sliced vanilla bread was left for us after cleaning one day, and a nice card was given to us when departing the unit. I would highly recommend Altea as an affordable place to stay in Santorini.
