Lucas apartment is right in the heart of historic Rome. Therefor it depends on what you consider "central". There are just a few restaurants and cafes around, but the market on Saturday morning next door was really nice.
The apartment was very clean, especially the bathroom seemed to be just renovated.
Although the apartment is on street level, it wasn't to loud.
All in all the apartment is more functional than cozy, but a good starting point to explore Rome.
