This is a great bargain! You are getting enough bang for your buck for sure. Room was great- spacious place in the the villa complex with poolside location. Car was worth it- hands down best way to get around the island (kicked in 10€ extra a day for an automatic Smart car- good for the drive to the other side of the island and to park wherever you want). Service was friendly- Rousettos squared away all of our traveling needs (trans to and from airport, discount tickets, etc.) and the villa manager took great care of us throughout our stay (breakfast every morning, fresh sheets and towels every day, even gave us a present right before we left).
I stayed at the villa for the weekend with my gf (we are both mid/late 20's). We were there for her b-day. It was perfect. Highly recommend Santorini! Highly recommend this property! 5 stars!
