This apartment is in a perfect location, with excellent views and a wonderful deck for lying in the sun. The main street of Oia is 10 minutes walk away, and everything you need from shops, restaurants and tourist advice/tours can be found there.
The 180 degree view definitely sells the apartment, however inside the apartment could do with a little more attention. John, our host was always available via message/telephone, and extremely helpful. He arranged transfers and a porter to help carry our bags down the steep steps to the apartment.
In summary, the location is awesome and with a little more attention inside, this can be a great holiday apartment.
