Great central location close to eateries and Metro. Literally 5 minutes walk from the Colloseum. Good communication. Gian Paolo organised transport from the airport, which was much appreciated after 26 hours of travelling!
The Lonely Planet book was well used.
Only negative would be that if you are a light sleeper, you may need ear plugs due to the usual noises of living in an apartment building. Not rowdy, but would disturb you if you are used to quiet at night.
