Great position in Oia. Villas are nice, air conditioned and good wifi. Beds are comfortable. Couple of things to note;
We specifically requested Villa 1 before booking and when we arrived it wasn't the villa we were given. Pretty annoying considering I specifically requested the larger 60m2 villa and not the 45m2 villa. Make sure you make it abundantly clear before booking and check in again on the lead up to your booking to make sure you get the villa you want.
Also for security conscious travellers the safe is not a safe in villa 2. It's a shoebox sized lock box that is not secured to anything - so anyone wanting to steal your valuables can simply break in and take the whole box. We therefore had nowhere to secure our passports and valuables. Wouldn't usually think this an issue except for the fact our villa was robbed in Mykonos only days earlier so wanted a way to secure our remaining items whilst in Santorini.
