Stayed here for four nights in June. Knew the hotel was in the outskirts of Rome but the convenience of the shuttle bus sold it to us. But what a huge mistake. Before we came here we spent three nights in a B&B in the middle of Rome ( Il Covo ) and thoroughly enjoyed the location and experience. When at the Melia though you could be anywhere, all sense of location is lost. Deluxe room was large and comfy but looked quite dated with some very dodgey electrical sockets, pool was ok and most of the staff were very pleasant. But..............
Food.......... Paid 70 euros for easily the worst meal that we had in Rome. Eat elsewhere or bring something back with you
Breakfast.....Jam excellent, rest of it mediocre. The bacon and sausage were very poor quality and the colour of the eggs need to be seen to be believed. Quantity there but quality poor
Shuttle bus.........If you are planning to use this from the hotel you must get ther twenty minutes early or you may not get a seat. Returning from Rome in the evening it does not matter what time you get there because the driver just opens both sets of doors and it turns into a mad free for all. We queued for thirty minutes and got left behind along with many others. Make sure you have enough money for a taxi otherwise it will be a long walk.(The queue at reception is usually not people checking in but people complaining about the bus)
Drink........Bring your beers back with you...8 euros for a small beer and 11.50 euros for a vodka and tonic, even at the pool bar. Don't plan a stag do here!
Internet........10 euros for 45 minutes
Car parking..........Did not use but 16 euros a night
As you can see you may get a good rate to stay here but once you are here there is absolutey nothing nearby hence the high prices I suppose.
To sum up, as an overnight stop this might be ok, but if you are planning to use as a base for exploring Rome keep well away, book this place at your peril. Find a hotel or B&B near the sights, you will have a much better time

I snagged a very cheap rate (less than 100USD/night), but I would still think twice before staying again. The hotel had difficulty understanding my fluent English and Spanish (ironic for a Spanish hotel chain). Do NOT eat in their "breakfast room" unless it is included in your rate. I was gouged $50 Euros for two "American breakfasts," which amounted to nothing more than coffee, juice, disgusting eggs, and chopped up hotdogs. Restaurant/bar food/room service was mediocre yet laughably overpriced. But, the grounds and rooms were immaculate: we appreciated the little niceties like surround sound in the bathroom, motion sensor lights in the halls, etc. Also, the shuttle bus to Ottaviano Metro station is a great plus. Do arrive early, though, or you may find yourself waiting another two hours for the next one. (TIP: Leave the Ottaviano Metro area ASAP. Shady area with terrible food.)

My wife and I stayed at the Melia Roma Aurelia Antica as part of a Trafalgar tour (Italian Holiday). The hotel while nice and clean was far away from Rome proper yet served our needs nicely as a jumping off point. The room was clean and well furnished – shower curtain/door was awkward which resulted in water all over the floor. Our only meals at the hotel was the breakfast buffet which was plentiful and acceptable.

Lovely hotel with stylish reception area . However, hotel is on outskirts this sounds ok as there is a free shuttle bus. But this service is completly over subscribed with only two buses back late evening one at 8:30 and the other two hours later at ten. If its full you are left on the pavement with a two hour wait or an expensive taxi fare of between 12-20 euros.
