We rented the entire winery complex for 10 people. It was a bit crowded in the main house, but not a problem for us as we knew each other well. The location is perfect for those wishing to stay out of the tourist fray. It was a bit challenging for the older folks in our group, due to narrow passageways and cobblestones, but manageable. Oia is a short walk from the house, and it's well connected to the rest of the island by bus and taxi service. There are several excellent restaurants right in Finikia, just a couple minutes away. Our kids loved playing with the many cats wandering around.
We enjoyed the authenticity of the house and appreciated the many small touches that make it unique. Internet was a bit spotty at times. The kitchen could be better stocked to accommodate cooking large meals. The small pool must be nice for a quick dip in the hot season, but the weather was not so great when we were there, so we did not use it.
Our host Daniele was wonderful - very friendly and eager to help. He helped us with transportation and gave us some great tips on things to do, such as an e-bike tour of Thirasia.
All in all we had a fantastic time and I highly recommend this rental for those who are less interested in luxury and want to experience some of the local flavor of Santorini.
