Objectively: Great view of the sunset; 20 minutes/30-40 Euros from Oia; 10 minute walk to Fera; Not easily accessible without a vehicle/taxi unless you are prepared to walk hills; Unit is simple and a little tight on space;
Subjectively: The apartment is located in a somewhat isolated community of units on one of the two main roads that cross the island. Road noise from passing wasn't an issue for us; Do expect to rely on vehicles if you are keen to get around the island, not everything is walking distance. From this villa you would have an uphill walk for about a kilometer before you are heading downhill to Fera, but then you are walking uphill on the return.
The upstairs unit is in a good state of repair; everything worked. Space in the bedrooms/bathroom is limited - for example you have to open your suitcase on the bed as there is not enough space on the floor to open lay a suitcase flat. There is cupboard space available if you are okay to unpack your suitcase entirely.
We had an unfortunate incident with the washing machine in the lower unit; it took some calls to get the situation looked at but to the manager's credit, he had someone nearby come around (this is around midnight) and start looking at the matter, and then the manager came by as well. They worked on the situation and left only after they had worked to correct the matter.
Ultimately the issue recurred the next day and had to be addressed again; we were given a credit by the manager for our booking.
Read the unit's description and reviews attentively as they will adequately prepare you for your stay.
