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.

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.

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

Liked: Staff & service
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.
