I had a great time in Mango crystal hotel, Miss Luo helped us look for the local attractions, organised our travel route and booked uber for us, I strongly recommend this hotel, you will have a happy adventure in Haikou.
The room was really amazing, with a great view. The family suite has two King size beds. It's quick to walk out to the beach.
I enjoyed smoking a cigar on the balcony. The breakfast buffet was great and the staff was very helpful, especially Butler Xiao Wu. This is a top line hotel.
