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.

Friendly and welcoming staff. Loved our stay here!!

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.

This was the best experience I had ever had. Staff was exceptionally kind and helpful. The rooms were stunning and clean. The complimentary breakfast was healthy and delicious.

Nicely tucked off in the narrow streets, with easy and quick access to clothing shops, restaurants and bars. It is a 5 minute walk from the ferry terminal and provides you with a clean and friendly environment to rest your head.

Beautiful hotel , staff was friendly and helpful Rooms where great , clean and comfy

A lovely property with amazing staff both friendly and very accommodating in a beautiful location.

The Castro Hotel was outstanding in every possible aspect. It was magnificently restored, the amenities were superior and the staff could not do enough to make our stay more than comforting!

I’m constantly amazed and disappointed in European hotels: (1) there are no doors or privacy in the toilet area, (2) in the 21st century can’t you make the toilet flush with a piece of toilet paper (?), (3) the shower has a 1” well that easily overflows, (4) the light switches are non-sensical, random, disorganized and cannot be figured out, (5) the A/C unit blew cold air up BEHIND the drapes (had to choose between a cool room and privacy). Positives: The breakfast area was very nice and the entire staff was great and accommodating.

Very comfortable, close to everything in Ermoupoli. Staff are very friendly and helpful.

A beautiful hotel with wonderful staff - highly recommended. Love the town of Ermoupoli and Ano Syros.

Excellent hotel with a warm and friendly staff!

Amazing hotel in a great location with lovely helpful staff. Would recommend and stay again in the future.

Beautiful accommodations and personal touches. The bed is cloudlike. The breakfast was beyond perfect. Will make this my place when i come back.

We had a magical and unforgettable stay at the hotel Castro during the winter holidays! Everything was perfect and dreamy, the location close to everything, yet quiet and serene, the room and common areas brand new, spotless and luxurious, the service attentive and professional, the ambience romantic and traditional, the breakfast delicious and abundant. Special thanks to Peppy and Maria for their warm and friendly hospitality! Stefania and Paul
