Lorenzo's apartment is not only perfectly situated to access all of the main sites of Rome on foot, it's located in the very charming & fun neighbourhood, Monti. Lorenzo described Monti as a village, which we totally agree with. It's a community with a beating heart, with lots of great cafes & restaurants around.
The apartment itself is small, but has all you need for a comfortable stay. Besides, you should really only need the apartment to sleep, there's so much to see & do in Rome.
Lorenzo is a great host; very accommodating, his apartment is immaculately clean, he offered helpful advice regarding our train travel and we appreciated the basics he provided for our stay.
One thing you should know is, the shower is very small/tight, so it might be difficult for a larger person to stay there.
Overall, it was a great experience; we'd highly recommend staying at Lorenzo's place!
