We spent a great 2 nights/3 days in Rome, and Fedra's home was close to the train station and an excellent base for exploring all the sights. We ate out for the most part (other than breakfast) but the kitchen was well-stocked and we could have easily cooked.
The only glitch was limited water pressure on the top floor of the building and kids who like to take long showers. Once we figured out how to adjust, it wasn't a big problem though.
