Roberta and her son Joyce were brilliant at communicating and got back to us quickly if we needed anything. Roberta gave us a lift back to the airport (a much better experience than the terrifying taxi ride from the airport) and was delightful. The flat is wonderful, and HUGE. A great place to hang out and to come back to after a busy day tramping round beautiful Rome (and very conveniently close to the metro line which got us everywhere we didn't feel like walking to).
