It's a fab place ... lovely location ... extremely easily accessible from the termini station to colosseo station on the blue metro & all off the attractions on foot if walking is not a issue ... v covered all the places on foot & didn't feel the need to take the hop on hop off bus ... but yes do take extensive tours of the colosseum & Vatican City from
A travel agent very close to the apartment .. walking distance .. extremely happy with them ... and the apartment is self sufficient with a super market in the next lane ..
