Wow - this place is magical and one of the best Airbnbs that I have ever stayed at. If the windmill is available don't hesitate to book it - after three weeks traveling throughout the mainland and various Greek islands, this was the BEST Airbnb that we stayed at.
The windmill is delightfully renovated and luxurious, with modern appliances (i.e. bathroom, kitchen, and wifi). The AC works like a dream, the bed is heavenly, and everything is spotless in the space. Stella is an amazing and attentive host: she dropped off an extra blanket for me at 11 p.m. when I asked. The windmill is super close to everything in Adamas, we just walked everywhere. However, we did have a car and there's a reserved spot at the Airbnb.
We spent one day in Milos exploring the island via boat. When we were pulling into the port at the end of the day, we could see this magnificent windmill from the water - it was a memory I won't forget! Again, do yourself a favor and book this one-in-a-lifetime windmill.
