noise staying near termini in Rome?

No. Vehicle traffic is much more an issue - as it is everywhere in Rome.

No, absolutely not. First off, they are electric train which make also no noise, second, they are coming and going from the station not passing through the station so it is all very low speed and the actually train tracks are some distance from the commercial area when most of the hotels are located.

Thanks for your quick replies...and for the info about electric trains.

Nope!

We found it very quiet and Termini's shops, esp. the grocery store were awesome. Plus the metro leaves from there.

We stayed in the flowers room with terrace at aromabb.it It was fabulous!
