This is a fantastic apartment/loft to stay in! The view is amazing, and the hosts are extremely kind and forthcoming. The kitchenette is small but quite sufficient; breakfast is generous and flexible, and main meals you'd like to take elsewhere anyway.
As in the rest of Imerovigli, and probably most places one would like to stay at in Santorini, getting to/from the apt requires descending/climbing some stairs. But the view is so breathtaking that you enjoy every step you take.
