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.

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

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.

Beautiful property, perfect location

If you have the chance to book a room at the Castro Hotel, do it! When planning our trip we thought we would prefer a hotel on the water or a room with water views, but boy, we were so happy we went with the Castro instead. The property is impeccably renovated, and the location perfectly situated in town - tucked away so it's quiet, yet close to everything. Our room was spacious, with a beautiful outdoor terrace to enjoy throughout the day. The breakfast service was another highlight - many options to choose from! Finally, the staff were welcoming, warm and always helpful. Overall, we highly recommend this hotel and can't wait to return some day!
