We had another reservation for Rome, but it was cancelled the day before our arrival. So we contacted Fabrizio late evening and we had to arrive next morning. I thought he wouldn't be able to take us in on such a short notice, but I was wrong.
On the morning we arrived, even though Fabrizio couldn't make it to the flat, we were met by someone else, who showed us around the flat.
The flat itself is not too big, but we felt comfortable - we were 3 persons. The flat is clean and has all the necessary things you'd need for a short stay in Rome. It doesn't have a washing machine though which might be a little bit of a problem if you're in for a longer period. The flat is situated very close to Termini station, so basically we had access to everywhere from there. But even on foot, the main attractions are not far away.
It was a pleasant stay overall!
