Jimmy's apartment is on the fourth floor of a narrow walk-up but not a problem if stairs don't bother you. Once in the apartment, you have terrific views of the Campo de Fiore which is always changing - from a fruit and veg market in the morning to an open square in the evening.
The entire square is surrounded by restaurants. So from morning to late at night there's an exciting vibe going on. Bring your earplugs. The market vendors start setting up their tents (clanking metal poles) at about 5:30 a.m. Being a sound sleeper, that didn't really bother me but it was certainly notiecable.
The apartment is spacious and clean. The bed would benefit from a mattress pad for a little extra cush since when I was there the sheets were directly on the mattress. Good hot water and excellent help from Jimmy's assistant's if you have any questions. The apartment seemed to be a good value.
