We had a great time at Marco's apartment.
The location is amazing, right in the center of the cool Monti neighborhood.
We really couldn't ask for a better location.
It's a walking distance from the city center and main touristic spots, but also has a metro station near by and various bus stations that can get you to farther places like the Vatican and Trastevere.
Marco was super nice and very responsive, and he's father who showed us to the apartment was very welcoming as well.
The apartment itself is very cozy and quit big.
It had all the amenities we needed and lots of art hanging on the walls which gave it a nice feel.
