The apartment is well located in Rome. You can walk to all the attractions in the old city, and just arround the corner there is a busstop with lots of connections, and a few hundred meters further away a metro station.
We( a family of 4) stayed in the apartment during July where it gets a lot hotter in Rome than we are used to, so we really enjoyed the central location, where we could get out of the Sun and take a siesta with aircon :-)
The apartment is well equipt, clean and to our surprise really quiet, there were no traffic noise, not even at the cosy roof terrace.
The hosts are really friendly and eager to help. When we arrived late in the night, and Paolo had bought us some breakfast for the next morning, so we could just relax, and didn't have to rush out and find a supermarket.
We can definitely recommend Cristina & Paolo and their apartment.
