As someone else wrote on their review: don't think about it, just book it. You won't regret it.
You'll get everything you need plus more. It is a very unique cave house, with beautiful thoughtful touches(and an awesome pool) Leonidas, Anna and Sophia are truly exceptional and the kind of people that make you feel like they're friends you have known your whole life. The location is beautiful,within walking distance to Plaka, and a short drive to anywhere on the Island. Anna sat down with us upon our arrival, explained in detail and showed us on a map, all the places of interest, best beaches to visit, which ones to avoid because of the windy conditions, best restaurants and bakeries, boat rides, everything.
We would definitely stay here again the next time we are back in Milos(we miss it already and can't wait to return).
