Marco’s place is located near Colosseo ( about 7 minutes by foot). During our stay we never used public transport because everything is can be reached in 30/40 minutes max walking.
Accommodation was clean and comfortable. Every morning Marco prepared tasty breakfast for us. If you are searching for an accommodation in center of Rome. It is right choice for you. The only thing that was disturbing was noise outside the building but it was very easy to solve it by closing windows ;).
