My wife and I stayed at the Ascott Star KLCC for four nights in January 2025. We spent a long time at check-in, as we arrived at 13:30 and the room was not ready. It was still not ready at 15:00, so the reception kindly gave us another, upgraded Apt (we had booked a deluxe one-bedroom). It was my fault as I did not indicate our arrival time in the online check-in. I suggest you do this if you plan to arrive before 3pm, especially if you arrive at a busy period (our stay was over the Chinese New Year holiday weekend). The Apt was fantastic; very modern, large, clean and well-appointed, with a view of the Petronas Twin Towers. The location is also great, within walking distance of the towers, but in a quiet area. We didn’t use any of the facilities but there was a lot on offer. The view from the rooftop is absolutely gorgeous. The hotel personnel were all very helpful and friendly, and we will stay here again when we travel to Kuala Lumpur.
