Monica's apartment is very central to the Colosseum and we also were able to easily walk anywhere we wanted in the city including Vatican City (2 miles one way) and the Borghese Gallery. If you are near the Vatican check out the Mercato Trifonale afterwards (it closes at 2 pm) for fresh produce, fish, meats, nuts, grains, and cheese for super cheap meals that you can cook at home (if you stay a long time like us). A closer outdoor market to the apartment is the Campo de Fiori maket, which we didn't have time to make it to. We loved the staying in the Monti district in Rome because it has so many food options, but our absolute favorites were Sapori e Delize which has delicious pizza, pasta, and vegetable salad (trust me you are going to crave vegetables by the time you leave Italy) and Fatamorgana for the most unique and legitimate gelato. Monica's place is great because it has an air conditioner and the place is spacious with a well-equipped kitchen. Monica was great and easy host to communicate with.
