Federico's apartment was perfect!
It was clean, sunny and the building was great!
The location is excellent, we never took any means of transport as everything could be reached on foot, even the Vatican 25 minutes walk. (Pantheon 7 minutes, piazza Navona 5 minutes, Colosseum 12 minutes)
Also nice places to eat around.
Federico helped us a lot by giving the opportunity of early check in and late check out.
If ever back in Rome we will defenitely first check if Federico's apartment is available :)
