To the suggestion about Tune hotel, definitely look closely at the particular one you would be booking. Some of them are just literally glorified hostels. I can suggest the Hotel De Palma in Ampang point. It is a little bit out from downtown KL and closer to the airport/track. It is fully Muslim compliant (great for me!) but depending on your tastes you might not like it. No alcohol served and not the type of place you could take um, “lady friends”. If you want great service, food, and a family friendly vibe then it is your place.
