I travel quite a bit, and I would say that this is probably the best service I've ever had from a hotel! Socrates was amazing. He went above and beyond. He even brought umbrellas to our room when we had a rainy night.
It is definitely worth it to get the breakfast - savoury pies, sweets, orange juice, croissants, homemade candied orange peel, etc -- all beautifully presented in a basket and brought to your door.
Beautiful place, very clean, great patio. Walking distance from the port.
If you are going to Milos, stay here!
