We had a great time at Giulia's place.
The room and bathroom were very clean. She had left some snacks, juices and water in the fridge for us.
She gave us all the info we needed regarding busses and trains getting around. either to the stadio olimpico, Fiuminco airport or anywhere we asked.
She helped us purchase online tickets for our Vatican tour and gave us restaurant recommendation.
The location is right on Campo di Fiori which is where you want to be, at the center, close to everything.
No worries regarding the noise. The windows do a great job of keeping it out.
We really enjoyed staying at Giulia and recommend staying at her place.
