The Mill Haven house is located in an ideal location in Oia. Close to everything, including markets and quad/car rental. Our host, Evelyn, was very helpful and responsive. She helped us arrange transfers and had a list of restaurant recommendations. We loved sitting on the rooftop deck and people watching in the jacuzzi, alongside some of the best views in the world! One thing to note is that the top bedroom is not connected to the bottom main house (separate entrance and you have to go outside to enter). This would be great for friends, couples, or families traveling with older kids, but was not ideal for us with a 3 and 7 year old (especially with the steep stairs). The house has a small kitchen, but had everything we needed for our 5 day stay. There were some plumbing/sewage problems in the downstairs bathroom the last few days (discussed in other reviews), but Evelyn was responsive in addressing. Overall, we really enjoyed our stay.
