The pictures do not do justice to Antonia's place. The place is spacious, clean and pretty close to the metro station (10 mins walking distance), where you can take the train to all the major points.
Antonia and her pretty daughter expected us at her place and gave us a tour of the house. She left for us a nice map (that proved super useful!) and lots of fresh fruits! She also provided towels and left a set of keys for every couple (we were 3 couples).
A piece of advice if you're visiting Rome: do buy the Roma Pass! For 2 or 3 days it gives you free access to 1-2 museums/sites and unlimited access to Rome's public transportation.
Thanks, Antonia, for everything!
