We hunted high and low for accommodation in KK and this was the best of a bad bunch. Apart from the places that are quite far out (like Masadas and the Beach places) the standard in KK really isn't very high at these prices. We got frustrated with other people on tripadvisor saying you could get better elsewhere, as they never say where you can get these elusive places....and as plenty of worse places were full, which probably indicates that the accommodation owners in KK do not really need to make much effort.
BGL was not your typical backpackers, like a hotel/office/student house combination. It was clean, and we had the family room which was huge. The staff were friendly and keen to help, although not always very knowledgeable or able to help!
The common area is OK, and the internet access is cheap. Location is fabulous, the Gaya street market starts on your doorstep, and the chinese restaurants are great - try the steamed buns if you get bored of the BGL breakfast which is the same as the western breakfasts you always get in hostels in Malaysia.
My advice? If you want to find a great place to stay in KK, then arrive early and shop around and try to find it. But if you can't find somewhere really special, then BGL is a reliable option.
