We had a great time at Giulia's appartment! Everything was clean and most rooms were even a bit bigger then we expected. Only the showers were a bit small for a tall person like me, but still good enough for a few days.
The centre of Rome is at walking distance (+- 15 mins), we only took a taxi to get to the Colosseum.
I would definitely come back to this appartment if I go to Rome again.
