It is a beautiful hotel with bright, spacious rooms. The restaurant is excellent—both lunch and dinner are highly recommended. The staff is friendly and competent, providing excellent service. I felt very comfortable throughout my stay. The beach is just a 5-minute walk from the hotel, and a lovely 30-minute stroll along the promenade takes you to the historic city center. I truly enjoyed my vacation. Thank you very much!

Stayed for 2 nights in May. The hotel is a close walk to the beach and on a main road if public transportation is needed. The room was clean and the bed was comfortable. The check in and check out staff are friendly and helpful. If parking is needed it is best to prebook with the hotel as spaces are limited, there is also paid parking a few streets over.
