Roberta's place is simply beautiful. Tastefully decorated with plenty of info on Roma! It's conveniently located, you're close to major landmarks (you can see the Colosseum from the window and you're 5 mins from Paletine Hill and the Roman Forum) and you have a 24hr Carrefour right in front of the complex.
Roberta was a great host and took great care of our needs! I've already recommended the place to my friends.
