The flat was as we expected. Everything was perfect: we arrived at night with small children and Massimo friend Gabriella met us and gave us milk, toasts and pasta to cook. So we could make a breakfast for children.
The location is perfect: 5 min by foot to metro station Bologna and 7 min to Tiburtina station. It took us 6 min by metro to get to the center of the city.
There are a lot of cafe nearby the flat, this was good but a little bit noisy at night: people at Rome never sleep:)) but we closed the window and switch on the condition and we can sleep.
Thank you Massimo : everything was good!
