Beautiful facility. Excellent design with practicality and modern sensibility. The breakfast was outstanding and great value. Service very attentive, professional yet friendly and authentic. Fitness center was on par with any five star hotel. Rooms were beautifully appointed and far bigger than any hotel whether four or five stars.
