The apartment is a wonderful place to stay in Rome! Very close to the metro, and the bus station from where you can go to the colosseum is directly in front of the apartment (it takes 20min). Nicola is a very caring host, who answered immediately to our questions and once, when the flushing of the toilet didn’t work he was there the same evening to fix it (unfortunately it didn’t quite work then either, but it should be fixed by now since the repair was after our stay).
From the roof you have a fantastic view over the city, especially at night.
We stayed there in a group of four people and had a lot of space since there are three rooms. We would recommend this place for a city trip to Rome!!
