NEVER, but NEVER, make a reservation of any room in this hotel, without the chance of refund!! We were not able to arrive at Milos the day we had booked a room (because our ferry was cancelled due to weather conditions), and they didn’t refund us a cent!
The cancellation of ferries in Greece is as common procedure, even in summer (we tried to visit Milos in September). Making a reservation in this hotel without the chance of refund is a totally trap! They don’t take in consideration that you were obliged to cancel your room reservation. You had no other choice and even so, they got all your money!
This hotel shouldn’t be allowed to give the possibility of making reservations without the chance of refund without any information about the risks you take. They act in bad faith since tourists are not aware of how it works the ferries’ system in Greece.
