There's a snack bar/deli on site. A computer station is on site and WiFi is free in public spaces. The business-friendly 1 Orange Hotel KLIA & KLIA2 also features tour/ticket assistance, laundry facilities, and an ATM.
Here is a possible re-write:
The staff are friendly and attentive. However, the lift is only for luggages, not for guests. It would be better if they could install a lift that can carry people as well - climbing the stairs to the third floor is not easy for those with knee problems! The air conditioner also needs servicing - the room is warm even at the lowest temperature setting.
