The appartment was great. We were 5 people and it fitted perfectly for us.
The location is near busses, trains and the metro.
It was very clean we have enjoyed our stay there.
If you are there, check out the "Ristorante Centro" around the corner or the Food Court in Termini station. Amazing as well :)
If I ever come back to rome with a few people, I am sure to book with Julian!
