Close to the airport means, small 5 minutes in the car, buss or taxi. My single room was extra small and 29 degrees when I arrived. TV was small and felt almost impossible to watch from the bed. Taxi from Fiumicino after returning my rental is €20, even if its that close. And you'd think that the hotels own mini bus would be cheaper, but it is also €20, a rip off for a 4 minutes ride. So if you absolutely must have a close hotel and just want to sleep, fine, but otherwise, I wouldn't recommend it.
