Nice non-tourist places?

Hi everyone,

My gf and me will be in Rome from Friday to next monday. We'll get a Vespa during these days to be mobile.

We assume that the city center will be crazy full with people (+ AS vs Lazio Roma on sunday).
Could you suggest us some nice places (cafés, museums, restaurants etc.) a bit outside of the city center that we can reach by vespa?

Grazie from Basel, Switzerland 👋🏼
