I stayed at Fabio's apartment for my six day break in Rome. I found it to be a great location for seeing all of the sights of Rome, a 30 minute walk from the Alter of the Fatherland, a 2 metro stop of the Vatican and a 6 metro stop from the Colosseum.
The Piazza del Popolo and surrounding streets had lots of lovely restaurants and bars which you can enjoy dining as well as numerous Gelato shops.
There's also a lift to the apartment so none of this carry bags upstairs.
For people who like the cook, the apartment is fully stocked with pots, pans, fridge, freezer - I was able to cook chicken, steak, numerous veggies and omelettes.
If you are feeling a bit lazy, there is also a Burger King down below.
I'd definitely stay here again.
