This place is amazing! It is located in the west part of Milos, in the middle of nowhere. It is a 20-25 min drive from Adamas. The road itself is an unpaved dirt road in good conditions, I would take a car, but it is possible to get there by scooter as well. The cottage is beautiful and comfortable. There is basic kitchen ingredients and equipment. We got an amazing cake from Sophia, and a warm welcome from her husband and her son Stamatis. They were super helpful.
There are beautiful beaches along the coast, keep in mind despite that the beaches are beautiful and you have them for yourself the roads are really bumpy, you definitely need a car or really good skills with a bike.
However this place is amazing to stay and explore the beautiful west part of this amazing island. We definitely come back.
