Loved this boutique, modern hotel! An easy walk from the ferry, beautifully appointed lobby, room, and restaurant, and comfortable bed/accomodations.

Probably the best hotel we’ve ever stayed in. I was a little bummed because their spa and restaurant was closed but their staff went above and beyond to make sure we were comfortable. The breakfast was the best food we had while island hopping too.

The staff and the spa were amazing and I will definitely be back. Such a cool property and the location was perfect, walkable from the port and right in the middle of where you want to be. Steps to the best restaurants and nightlife we couldn’t have asked for a better hotel to stay out. Loved everything about it! The prestige suite is amazing!

Outstanding hotel. The customer service is incredible. We went for our honeymoon and they made us feel so special and really looked after us. The spa was fantastic and could not speak highly enough. Will be retuning again. Thank you Castro Hotel for making our honeymoon so special.

Premier luxury hospitality

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

We stayed at the Castro Hotel and absolutely loved it! The location is ideal for exploring the city of Ermoupolis and walking through the alleys. This boutique hotel is truly a piece of art, with every detail in the rooms, from the design to the decor, being carefully thought out. The staff was friendly and helpful during our stay. We loved our brunch at Aithrio Lounge and also our drinks and wines at Cellar 1857—a very atmospheric and cozy wine bar right next to the reception of the hotel! We were able to enjoy some quiet time in their spa area, which was clean and rejuvenating with a jacuzzi and hammam. Overall, this hotel is a small gem hidden in the heart of Ermoupolis.
