We checked out one day before around 9 am in the morning but they told that you should have told earlier so as to refund.
Moreover they are a travel agency so i booked sea jet ferry from them. However the tickets got converted to a smaller ferry which took 6 hours. All passengers got the refund back as ours was private jet. We asked them they are just not giving the refund and just saying for refund you have to come to milos. For 40 euros they want me to spend another 500-600 euros to come to milos from india.
I think greece is having internet banking facility and international wire transfers but they havent responded yet.
However, the host was very excellent as they recommended amazing places, where to go. We had a wine as a welcome gift.
One night stay was good
Apartment is good and has a great balcony to chill.
