We really loved staying at Cynthia's and Tatiana's home. We came in by train and the apartment is right by an excellent train hub. 2 minutes from the train and we arrived. Cynthia gave us a wonderful welcome and a very helpful orientation to her home and to the neighbourhood.
The apartment seemed bigger than the pictures and is very well equipped. They had stocked the home with some basics like milk and bread that saved us a trip to a grocery store that night. They had maps and guides laid out too. There were four of us staying and we all were very comfortable. An ensuite bathroom was a big plus. We also loved the fast WiFi which worked consistently throughout the house.
The neighbourhood is perfect. We walked everywhere, except for a bus ride to the Vatican. The Coliseum is 20 minutes away. Campo del Fiori (a lively morning market) is just 5 minutes away. 10 minutes and you are at the Pantheon. We would also recommend the Travestere neighbourhood which is a great place to eat in the evening. Just left out of the apartment, across the bridge and you are there.
There are a number of cheap eateries right next door with an excellent Pizza by the slice place right around the corner. Coop stores were also nearby for groceries.
Again, the place was super comfortable and we highly recommend.
