This apartment was perfect for our family of 4, with three bedrooms and two bathrooms, which suited us perfectly. One thing that we found that differed from the description of the apartment and the other reviews listed was that it was not as easy to get to and from central Rome as we had thought. During the day, we usually took the number 3 tram, which was fine. However, after about 6pm, the trams seemed to become more erratic - we waited 45 minutes for a number 3 from Trastevere one evening. Furthermore, we found the number 71 bus to be atrocious. The one time we did manage to catch it, which was around 8am, was after waiting for 30 minutes, and the next couple of times we tried, multiple buses did not show up. On our penultimate night, we waited around 50 minutes, by which point there should have been at least 3 if not 4 buses, and we saw none going in either direction. This was extremely frustrating and made us all really angry at wasting our limited time in the city.
In addition to this, it is worth noting that taxi drivers will rip you off massively - hence our insistence on taking public transport. Gabriele informed me that the best way to get from the airport to the apartment was to take a taxi - a flat rate of 30 euros from Ciampino and 48 from Fiumicino, which is printed on the side of the taxi. He even told us where to get dropped off so that we would be within the Aurelian walls - where the rate applied. We asked multiple taxi drivers to take us to inside the walls for 30 euros and they flat out refused, were argumentative and rude. If you are travelling here it is worth knowing that the taxi drivers will do this, and it might be better to get one of the airport shuttle buses to Termini and then walk from there.
Finally, it would have been nice to have something left for us in the apartment when we arrived. We really don't expect a lot, but our host knew we would be arriving late in the day, and it would have been thoughtful to have left some milk or even just some water in the fridge for us when we arrived. In addition to this, the only face to face interaction we had with Gabriele was when we checked out, which we all found to be quite awkward. We were told the check-out time would be 10.30am, and so were quite surprised when Gabriele showed up at 10.25, whilst we were doing our final checks and bathroom trips. Despite trying to engage him in conversation, he didn't seem very interested and in fact seemed a little bit annoyed that we were still there, which wasn't the nicest way to end our trip.
Ultimately, the apartment itself is great, and we found a lot of nice places to go around San Lorenzo. However, if you want to do a lot in central Rome, I would consider what I have said about the transport options before making this booking.
