We didn't meet Diletta, but her mother was very kindly and answered to our questions very comprehensivly.
The place was as discribed and located close to the colosseum and bus and tram.
We found some water and juice, coffee and biscuits when we arrived, that was a friendly turn.
I've missed an air conditioner because it was very warm at night in the flat.
But we have a great time in the flat and Rome.
