The apartment is just what it says - a really central just within the closest block to Pantheon. Lots of restaurants nearby and you can walk to most sights. With the restaurants come some evenig (->00/01) and early morning noice.(6-7) In our party of 8 (4 adults/4 kids 10-13) some were bothered by this, some were not. I guess how you perceive it depends on how sensitive you are to noice.
All in all definately a place to consider on my next travel to Rome.
