Lorenzo was an extremely responsive and helpful host. The location of the apartment is quite convenient. Only 5 minutes from the Metro station and about 15 minutes from Roma Termini the main regional train station. Just a tip, it's better with luggage to walk along the street parallel to the street along the station rather than the street adjacent to the station which doesn't have the best pathways.
There was an issue the sofa bed in the lounge room which Lorenzo attended to promptly the next day while I was out sightseeing.
The apartment is larger than expected and could comfortably fit one adult in the lounge and one in the bedroom or two couples or a family of four.
Lorenzo provided a bottle of wine, soft drink, fruit juice, snacks, coffee and tea on arrival which was very much appreciated. I didn't end up drinking the wine but it was a nice touch. He also provided two metro tickets which I didn't use because I got the 3 day pass.
Unfortunately the issue with the sofa bed returned but Lorenzo wasn't in town and I only had one more night to stay so there wasn't much that could be done. If the issue with the sofa bed is resolved I would recommend the place for anyone wanting to be based in a reasonably roomy apartment with a kitchen and lounge room for sight seeing in Rome. Given Lorenzo's responsiveness I am guessing that it is being attended to at the moment and should be resolved.
