My girlfriend and I loved our 4 days stay in this apartment. It's in walking distance to major tourist points like Colosseum, Pantheon, Vatican, Piazza Navona, Castel Sant'Angelo, Roma Forum,etc. Lots of restaurants nearby. The apartment is very functional, spacious and clean. Wifi works, bathroom shower has good pressure and hot water. We used the washing machine, so it works too.
The only thing that is important to say is that It is on 3rd floor! No lift. You have to climb those stairs. For us it was not a problem at all but for someone else with physical limitations can be a problem. That said, if you are lucky enough to find this place available dont hesitate and make your reservation. You cant go wrong.
