We had the most amazing time in Santorini staying at the studio 3 of Hara's House. The view is amazing and you'll never forget it! The studio is so well located on the island, in between Oia and Firostefani. Less people there, less calm and even more beautiful. The service in the studio is perfect, Stamos is the nicest man ever, he helped us in so many ways! Anna was so nice by email as well. The cleaning lady was adorable. You have air condition in the studio and everything you need is inside. It's very clean as well. The little pool you share with the other studios is just perfect if you are too hot and not many accommodations around have a pool so it was as well why we chose this studio. The local people are so lovely, the restaurants are really good (I recommend Aegeon) you have supermarkets, coffee makers, car rental all around.
I will definitely come back in this studio next time I'm in Greece.
