We stayed 3 days at the Eurogarden in Rome. It is actually not in Rome, it is off the Autopista on the north side of the city.

Perhaps the nicest feature of the Eurogarden is the setting. It is a group of single story attached units in a park like setting among pine trees. Does not seem like you are in Rome at all - - very nice setting.
It is a bit difficult to find. You need to drive on side roads at least for a half mile to get to the hotel. But it is worth the search.

This is best suited for people with a car. In fact, it would be almost impossible to conveniently stay there without a car. Prices are good.
Breakfast was excellent.
