We booked the apartment for a 5 day stay.
It was a bit far than i expected it to be. Even though you see it close to Termini and the city center be prepared to walk a good 40 min.
The metro in front of the apartment only gets you so far, because you have to change it to with the A line and in order for you to get to the A line you have to change at Lodi station, meaning you get out of the metro at Lodi and either hop on bus (51) to San Giovanni or walk 10 min.
To be honest this was the only inconvenience.
The supermarket downstairs has everything you would need, also the fruit shop (the fruits and veggies are always fresh). On the left side of the building there's a great pizza place and an Indian restaurant so you pretty much have everything you need.
Valentino and Andrea were kind enough and booked us tickets for the Vatican and the Colosseo with a guided tour which were definitely worth it.
They gave us little tips and were available to answer when we needed it.
Thank you for a lovely stay and we hope to come back soon.
