Spent 4 nights at the Hilton in Puerto Vallarta, and had a wonderful vacation. The hotel is beautifully done, the rooms are modern and clean, the staff is wonderful, the food is very tasty. For the first 2 nights, it was very cozy; not a lot of people in the hotel. By Saturday, it had filled up, which wasn't bad; the guys in the next room were partying loud when we wanted to sleep; the management took care of that very nicely.
My only complaint is that we were on the 5th floor of the tower, and it was very musty; when we checked in, the mold/must smell was overwhelming. Keeping the AC on and flowing was important to keep the room tolerable. Please, Hilton, fix this problem, and you would get a 5 start rating.
