Apartment was very clean. Within walking distance of most sites, as long as you enjoy walking.
The main street by the apartment was full of life.It was closed twice when we where there, once for a very large union demonstration and once for a Catholic parade with the cardinals and a lot of first communion children..
we would recommend taking a cab to the Vatican Museum, but you can walk back. Just sit for a while after the tour and then walk half way back and have dinner. You get to see a lot of sites this way.
Enjoy Roma, It is an amazing city.
