Check-in was smooth, the facilities were as per the information in the app, but for my second stay, the room cleaning took quite a while, from 7am, I just left, and it was only done at 4pm, due to the large number of guests, there were 40 rooms to be cleaned. Perhaps this could be anticipated by having additional temporary staff, as having many guests is not a reason to take longer to prepare the room, instead, the large number of guests should be a source of pride that Amaris Serpong is a favorite place to stay.
