Really great place to stay when in Santorini. Super clean place. Communication with host was efficient. Host provided for pick up and drop off at the airport at 1am and 6am! He didn't even want to charge me! If you stay here don't miss the Old Barber Shop cafe that is just 60 second walk from the front door. Also conveniently located near another cafe, a pharmacy, and a supermarket. There is also parking available right near the apartment. You do have to walk up some mildly sloped walkways to get to the place but trust me it is well worth it. My family loved staying at the Castle and wants to go back soon! Great view of the sea and the mountain/hill. Bonus is you get to see a beautiful sunrise every morning if you choose to!
