1) the aircon system is so old n noisy. Unless you can survive without aircon in the tropical weather, it roaring noise constantly was unbearable and unpleasant.
2) I rate it as paying a 5 star hotel rate for a 3 star hotel experience, especially by Chang Mai standard. I thought i would get a comfortable & restful & pleasant stay in Chang Mai. Disappointingly, none of that i experienced.
3) tried to ring front desk on at least 3 occasions on the first 2 days, it rang out and no answer and no call back. Until another try at 1:30/2 am as really couldnt sleep due the noisy aircon then finally got a response; yet hotel couldnt solve the problem which appeared that they were well aware that their old aircon system noisy issue or at least had had complaints before.
4) the restaurant downstairs was packed to being unpleasant the 4 mornings that i was there, felt like more of a 3-star group tour class hotel. I chose not to dine there.
5) it is right next to a night market and not many 5-star hotel class appropriate range of restaurants or bars
6) the 1.2 m deep only pool and was used by kids, perhaps due to the kids pool was closed for repair. Again for a 5 star hotel, one would expect at least one if not more decent swimming pools.
7) as i checked in, the room rate that i was charged for a Melia room (which was the lowest grade) through a Hotels.com booking was the going rate of a premium suite at time online. I didnt feel the hotel was trying to improve that disappointment.
