The apartment is very nice, big, with a nice daily zone (living room together with dining room/ kitchen) and a relaxing bedroom. It was very clean and stylish. freshly renovated, it looks brand new. Outside you have a nice little patio and table. The hosts were warm, taking care of us and amazing.
However, plz bear in mind that the flat is located in the middle of nowhere so you absolutely need a car to get there (but in general you need a car on Milos island), I also don't advise you to drive back to the apartment after having drunk any alcohol (typical practice in Greece ;) ) as the road leading to the apartment is narrow and very demanding.
I missed not having WiFi but it was stated in the advertisement so it was only my fault that I had overlooked it.
Other than that everything was perfect as we were very happy to stay there!
