Seriously stop looking at any other place on Milos.. this is the BEST place to stay! We stayed 6 nights and loved every minute. They picked us up from the ferry, gifted us a bottle of home made wine, and gave us necessary advice on the departure ferry (we would have arrived 8 hours early to the docks..)
The place is in a cute little part of town, walkable to grocery stores, shops, the main town, and scenic areas. Good wifi, clean and cute place with kitchen, would highly highly recommend!
