Federica's place was great to stay. It's very clean, has a comfortable bed, great AC, and a nice bathroom. It really feels like you are in a hotel. It was a little tricky to get up to the room upon first arrival, but Federica left very detailed instructions on how to get into the apartment, which was helpful. Location wise, it's very close to the train station which is practical for traveling days. However, potential visitors should know it's not super close to most of the main sites and fun areas of Rome, so we did have to pay for a few cab rides back in the evening because we were too tired to walk all the way back. Federica arranged breakfast tickets to the cafe around the corner each day, which was very nice. We each got a free croissant and cappuccino, which were both delicious! :)
