You cannot go wrong with Paolo's apartment!!! Fabulous location, well decorated, modern and Paolo is awesome. Very comfortable in short.

The apartment is a short walk from the Piramide metro plus a train station. By metro the coliseum and the main ruins of the Roman empire are only two stops away. And if you are leaving/arriving by air - the train station has a local train that is very convenient to the airport. You can also walk to the main ruins of Rome and some of the other sites - I highly recommend that as it is a pleasant walk.

There is a wonderful high-end gourmet food store nearby called Eataly where you can buy delightful bread and prepared goods as well as basic food stuffs. Definitely try the bread...

Paolo was fabulous - he picked us up at the metro and also gave us a ride to the train station saving us from being drenched in an awful thunderstorm. He is very well organized as there are sheets of paper describing nearby restaurants/sites. Paolo is a very genial person overall.

The only possible downside for some folks may be that the apartment is on a relatively busy road - so if you are the type that needs quiet while the windows are open this may not be the apartment for you. But there is an air conditioner so no need to open the windows in summer.
