Our stay was very brief (one night), but I would definitely recommend staying with Flora and Akis.
Our ferry arrived 45 minutes late at 11:15 PM, but Flora and Akis were there waiting for us and happily drove us to the rental property in their car to make sure we got there without any issues. There were two beers in the fridge and a bottle of water waiting for us.
We were just there the one night, but it was very clean and spacious, and the location was great for an easy walk to the Adamas Port area and just about a block from the rental agency (one of the ones Flora had previously recommended) where we got our ATV. Flora also allowed us to store our bags there while we waited for our other rental to open up in another area of the island.
As many have said already, Flora is full of information and tips about Milos and is happy to share them and give recommendations. Our Greek is nonexistent, but her English is great.
I would highly recommend a stay at Villa Flora Akis.
