The apartment was really nice, modern and clean. The only two things I have to mention are that there are no thick blankets, so it was a bit cold at night. Also, the kettle was very furred up so you could not really use it.
The apartment is very central, as it's close to Termini station, but you need to take the bus to most tourist attractions. Fabio was a really nice host, the communication was great and he gave us some great tips for restaurants etc.!
