Magnums is in a great location, right in the heart of Airlie Beach. It has a large bar and nightclub attached to it too. The shared shower and toilet facilities are also pleasant.
However, we woke up on our first morning with our bed covered in hundreds of ants, as well as a number of woodlice and small cockroaches in the room. Unfortunately, all of the rooms were fully booked so we could not change to a different room - reception did provide some bug spray, which killed most of the insects but there will still a few crawling around the following morning.
3 stars as the location and price were very good, but of course let down by the insects!
