Frederico's place was so wonderful for our stay in Rome! Key features we loved were the rooftop terrace (AMAZING!!) and the location! We were so close to everything and were able to walk everywhere- 5 minutes to the Coliseum and Roman Forum, 15 to the Spanish Steps, Trevi Fountain, and Piazza Navona, and 25 minutes to Piazza del Popolo. And walking was the way to go! There were so many wonderful side streets and places to explore on our adventures to these key places.
I want to add that we had ZERO issues with noise. We stayed on a Friday and Saturday night on a holiday weekend, and we had peace and quiet the whole time. We did close the windows and the shutters, which may have been why!
Places to check out nearby:
La Cassetta a Monti (great little coffee cafe)
Bar La Licata (Take away cocktails!)
Alimenteri Vini Oli- not sure if this is the name but it's a small little shop on Via della Madonna dei Monti with incredible low cost wines, fresh buffalo mozzerella, and a SUPER friendly man who is helpful and speaks English very well :)
