Fantastic stay in Milos! Our host, Cris, was amazing and super hospitable. He was always available and super helpful in any situation we ran into. Additionally he would bring breakfast every morning to all the units at the AirBnb, which let us get our morning coffee fix after some late nights.
The area is a bit out of town but still very much walkable to the port area. Definitely arrange transport for arriving (Which the host actually picked us up) and leaving the AirBnb if you have luggage as it is a dirt road. We personally rented an ATV nearby which was super suitable to get around the island.
The apartment itself is functional and cozy. The WiFi in the entire area was fairly stable except for when the winds picked up very strongly, however Cris ran a hardline from the router to the apartment for us so we had stability for video calls.
10/10 would highly recommend and stay again in Milos
