I can highly recommend staying in Emanuele's apartment.
The apartment is very cozy, clean and the terrace is amazing. I loved staying there and should I ever go back to Rome, this will be the first place I'll book.
The area is well connected, and close to the train station. Public transport for the city is also close. Although the apartment is in a neighbourhood with some nice bars and restaurants, it's very quiet inside. The neighbours were also friendly.
Communication with Emanuele was very good. He's a very kind and warm person, and he responded swiftly to any questions I had.
