Antonio met me there on the first morning at a time suitable to me. When there was a minor issue with the property, he showed up promptly to resolve it - on a Sunday! and knowing that I was leaving the following morning at 10am in any case. So very helpful indeed.
The flat is a lovely place - quite sparsely furnished (it could do with one more armchair and a chest of draws in the bathroom) - but with attractive views of the balconies and terraces in the area. It is beautifully positioned right in the heart of Trastevere and in easy reach of much of the more attractive areas of Rome, and just 1 minutes from the Tiber and the famous Ponte Sisto bridge.
