Ok. Mixed reviews for this place, but it was one of the best places I stayed at on my trip. As people say, there are 2 sites, (1) on the beach, noisy, and (2) across the road, more peaceful.
The across the road rooms are in 2 buildings, and this means 3 categories. Category 1 is the downstairs rooms in the 2 story building (this building is designated 'E') which are cell like, but appeal to the young and the frugal with their 60RM price tag. Category 2 is upstairs in this same building : 100 RM for a room with one large bed and 1 small one, (a/c, fridge, hot water) and this is a good deal, but it seems to appeal particularly to those who are taking advantage of the cheap alcohol on the island and who want to kick on by partying into the wee hours on the varandah outside their room with their close personal friends.
If you are such a person, please remember that there are others close by who are trying to sleep.
Better by far for the less gregarious is category 3, aka the 'D' units, a series of freestanding pairs of single story units on the left hand side when viewed from the road costing a very reasonable 80 RM. Units D3 - D10 are a comfortable distance from the road.
Good points - a big room, a/c + a fan, a fridge, hot water, queen size bed, peace and quiet.
If you're picky - no remote for the 3 local channel TV, you have to ask for toilet paper (all of 80 sen in any nearby store), and, the windows are clear glass. This latter quibble is only for the non exhibitionists.
Summary : great location, good prices.
Warning - the liquor choices at the duty free stores at the port and in the main town are far wider that those in the stores at Canang. If you want the 2 litres of JW Black for USD45, no problems, but if you're looking for something more exotic, the shops in the town should be your first port of call.

Good place to stay, there is cheaper but not anywhere I stayed as nice as AB. Some people complain others don't, i guess it depends on your attitude and a little to do with luck. I stayed there for about 2 weeks and didnt have any complaints. The resort is popular because it's reliable. As two young girls travelling we found it very welcoming and found that we wanted to stay a little longer because the routine became welcomed for a while. The beach is nice but is becoming increasingly touristy.
'Tomato' restaurant is fantastic, lovely staff and cheap cheap brilliant food. ALSO for lunch there is a lovely older lady on a stall selling all sorts of goodies.
Langkawi is a lovely retreat and I believe AB is definitely worth it...

Have been travelling to Asia and especially Langkawi for several years and stopped at AB several times. After this years visit and stay at AB Motel in January & February 2012, l will never stop here again!. Firstly the positive point, if your willing to pay 120 Ringgit for a terrace bungalow on the beach side of the road you may get a balcony with a great sea view!.
Thats where the positives end!, the negatives are as follows:-
1. Staff attitude customers is awfull & you get the feeling because AB is always busy, they no longer have to make any effort for your business. There attitude seems especially worse towards western visitors!.
2. Rooms are clean but very basic, no toilet rolls provided, no water!. Lack of power points!.
3. Beds are just exceptable but with what appears to be sand bags for pillows!.
4. Had prolem with constant running water in bathroom for several nights, attempts by maintence men failed & had to wear headphones to block out noise & try to sleep!. Staff attitude was basically we dont care!
5. Cenang beach has developed very fast over the past few years, it is becoming very expensive & hectic!, you can liken it to Aonangs demise in Krabi, Thailand!.

We stayed here for three nights in January 2012. The rooms are clean and modern and good value for money.The only criticism I can find is that our room did not have a safe and was very light at night because of the corridor lighting outside.
However I would recommend them as a good place to stay
