I had a great stay with my friends at the diamond house.
The house is a 15min walk from Fira, so we were able to go there every day. From Fira you can take the bus to other cities like Oia.
Sofia was very responsive and very helpful. She arranged a bus transfer for us from the airport to the house and from the house to the port at a very reasonable price.
The second day she offered us a delicious Greek pie for breakfast.
Would definitely recommend this house for people who want to stay away from touristic areas.
Thanks again Sofia for your hospitality, and a bientôt maybe :)
