Federica's place was very nice and very close to Colosseum. It is also very close to restaurants, cafe shops, convenient stores and public transportation. Pretty much all most famous sites are about 30-40 minute walk from Federica's apartment. The place was very clean and stylish. Towels shaped in swan shape was a nice touch. Throughout our stay Federica was very helpful and communicative. She has suggested what to do and places to see. She was there to help out. I highly recommend this place for anyone who is looking to be at the center of action right after they exit the building.
Only suggestion I have is to be upfront about tourist tax in Rome and share that information if not before booking, right after the booking. It is 3.5 euros per person per day.
