Staff is okay, location is not so good. The hallway is hot, the central AC doesn't work. Dusty, looks like it's not maintained. Worse, I was on the 16th floor facing the city main road, it was so noisy... The glass is really not soundproof. OMG I couldn't sleep all night, I had a headache. The AC wasn't cold enough in the room. Everything else is still forgivable. But for a 4-star hotel, this isn't the best.
