Monica's place is very centrally located, with all the main attractions just a short walk away. There are several really good restaurants literally a few metres away from her place. The area around the apartment felt very safe, even late at night. We were provided all the amenities that you would expect in a hotel , and more. Her apartment is on the 4th floor of a building with no elevator, so if you have heavy luggage, its going to be a bit of a struggle.
The apartment has a nice terrace, which gets lots of sun, and is especially nice in the winter, which is when we visited.
Since her place is so centrally located, it can get a bit noisy at night, from all the restaurants etc. But overall, Monicas place was clean, tidy, and a great base for exploring Rome.
