We've had a great stay at Federica's apartment. Federica was very hospitable and is absolutely a lovely host. Our stay exceeded all possible expectations. I sincerely doubt that there is any better place to stay in Rome for this price or even double the price. It's like staying in a hotel; beds are being made every day, bathrooms are cleaned on a daily basis and even simple but satisfying breakfasts are included in the price.
The apartment is brand new, well isolated, with very comfortable beds and on a perfect location, close to the vatican and a 100 meters away from the metro.
Thanks for making our stay memorable, Federica. We will definitely come back in the future.
