Giovanni messaged early on to confirm when we would come which was quite nice. We had some last minute changes moving out from our previous accommodation so I had to change the time when we would arrive to leave our luggage and he was accommodating of that. The house was very neat and well kept with all required essentials. We had Giovanni's girlfriend welcome us with helpful tips and maps. They also gave us a portable WiFi device. Though we did not have to use it, this would be handy for someone without a data connection and was a thoughtful gesture. The house is close to the metro line A station. We had a metro pass so it was very convenient to get around. The bus connectivity was also good. On our last day, he also offered us the chance to stay longer than usual checkout since no other guest was expected that day which was again a thoughtful gesture.
The only thing was that this the last station on the metro line so you may not be the closest to sights such Colloseum in old Rome. However it is close to the Vatican station and the metro is frequent and distance between stops quite short so should not be an issue. An advantage would be that you get to have a seat on the metro since it is the first station on the line and less crowded at the time.
