If you have a long layover in Abu Dhabi but still not enough time to go into the city, you have a number of options at the airport. Landside there is the PremierInn, which is connected to the terminal via a walkway. But there is also the airport hotel airside within the terminal. Directions to the hotel are clearly signposted upon entering the terminal building.
The hotel is operated by Plaza Premium lounges and is located in terminal 1, which is about a 5 minutes walk away from terminal 3. The rooms are clean, modern and functional. They even provide you with shampoo, shower gel and a range of other amenities.
The charge for a twin room is USD168 for a minimum of six hours.
