Lena has been an amazing host. She helped organize transport, reserve the restaurant for our first night and organized a sailing trip (which was by far the best thing we've done in Santorini). She also checked in several times to see if we needed anything and provided very useful advice.
The villa is beautiful, with a view on the sea, and very close to Oia. Perfect for couples.
Beware that Oia is very expensive and touristic. It's beautiful, but I would advice to go outside of the city if you want a typical Greek diner. We went to To Limanaki, a very nice Taverna with great staff.
