Kuala Lumpur doesn’t get nearly the attention that its nearby neighbor of Singapore does, but in many ways they are quite similar and KL is noticeably cheaper as well. It’s a very modern city that nicely blends genuine Asian experiences and culture with a slick facade that makes visiting quite easy.
Hotels in Kuala Lumpur can be great bargains, especially near the top end of the range. You can sometimes find rooms in legitimate 5-star hotels for what you’d pay for a 1-star hotel in London. Lower-end hotels and even hostels offer quite good value in Kuala Lumpur as well. Standards are generally high in all but the absolute cheapest hotels.
Partly since this isn’t a hugely popular tourist destination for Westerners, most of the attractions are priced more for an Asian budget, so things should seem cheap to most people.
Food can be another great bargain in this city, with a wide variety of cuisines available in all price ranges. If you head to the outdoor food stalls like the locals you can get some excellent fare at very reasonable prices. Drinks can be relatively expensive in bars, though in markets prices are rather affordable.
