We were 3 couples who recently stayed two nights at Federico's place in Rome.
Pros- Very close to the Colosseum and public transportation
Close on street parking
Nice terrace to sit on although it was not open when we were there.
3 nice size bedrooms each with its own bathroom
Elevator in building
Great little breakfast in the cafe next to building for 5 euros
Cons- Super involved check in process that was extremely confusing. Once we understood it, it worked well.
Terrace over looks very trashy area.
Kitchen was not that great and everything seems to be falling apart. Looked much different than the pictures online.
Beds were extremely hard and uncomfortable although some may like that

All in all it was a good stay and a good value
