Its not brilliant and to be honest, there are better options a 30 minute cab ride away.
Close to the airport is either Al Raha Beach Hotel or the new Shangri-La which would be my choice as its lovely, but maybe pricey.
Other options on a direct road to the airport would be the Intercontinental or the Hilton. Both of these are in Abu Dhabi but a taxi ride would be 30-40 minutes and cost around 10 pounds sterling. Just make sure the meter is on, and if you are travelling after 10.30pm/11pm, then agree a price first. almost 10 years ago
