Excellent location, literary 30 seconds walk from the harbour. Room was compact but we had everything we needed. Shower drain needs improving, water very slow to drain after two showers. Being located on the ground floor next to the front door we experienced noise of guests coming in and out at night. Breakfast buffet was small but excellent quality with à la carte egg dishes also available. 15 mins complimentary massage in the spa was a nice touch and the WhatsApp concierge service was a life saver for organising taxis and beach club bookings.

We had a wonderful stay at Castro Syros. The hotel is ideally located within walking distance of the port and the center of Ermoupoli, making it easy to explore the town, shops, and restaurants. The staff was outstanding - welcoming, helpful, and genuinely hospitable. Despite being so close to the action, the hotel is situated on a quiet street, providing a peaceful atmosphere and excellent rest. We would gladly stay here again.

Castro Hotel welcome could not be better. They met us with a taxi at the ferry, greeted us warmly at reception and made us feel very welcome. Hotel is charming and very central.
