It was a great experience staying at Claudia's appartment. There are buses, trams and a train near the appartment so getting to the centre is really easy. For us, the biggest advantage of the appartment was that it is located near the Tiburtina Station. Our bus departed from it so getting there by bus in the morning was very easy and quick.
Claudia was really nice and always prepared to help us. We had to check out early and there was absolutely no problem about that either. She was really friendly and gave us a lot of useful information.
All in all, our stay at Claudia's was great and if we ever return to Rome, we would be happy to stay at her place again.
