We had a fantastic stay at Rosa's place. The apartment is ideally located for visiting Rome, just a few minutes from the Vatican and a comfortable walk into the city centre. There's a subway station close by too.
The room was fantastic, perfectly clean and comfortable with our own balcony access where we could sit outside. Bathrooms are in great condition and we loved the breakfast too!
A great tip for dinner is Pizzerium Bonci, just a couple of blocks away and popular with locals and tourists alike.
