Was at Erbil in 2012. Nice and modern Airport with the longest RWY in the Middle East. Erbil is a very rich city and considered the "other" Iraq where it is rather safe and you can see the wealth around and in the city. Expect security checkpoints on main roads but if you have a local guide no problems expected. Best hotel is the Rotana at Erbil. Same style and comfort like you would expect in Dubai for example. Enjoy!
