We had a great few days in Rome and Lorenzo's apartment provided a great base. It is situated very close to all the tourist hotspots and we walked everywhere. There is also a taxi rank within a minutes walk where we picked up our cab to the airport. The flat is airy, clean and comfortable. We had a few great nights sleep. Super comfy bed. There are restaurants below but with very little noise after 11pm. They really didn't bother us at all.
Lorenzo was very nice, replied very promptly to all emails, was helpful with all our questions, flexible in terms of us meeting us an hour earlier than expected, and the icing on the cake was him letting us leave our baggage in the apartment until 6pm on the day of our check out as we had a late flight. Would certainly recommend.
