Andrea's apartment could not be better positioned, the Coliseum is literally just outside the front door along with bars, restaurants and a 24 hour supermarket. The Colosseo metro station is only minutes away and only 2 stations away from Termini station for both regional/long distance trains and access to the rest of the metro network.
Andrea is a fantastic host and took the time to step us through where the information centers were and some tips for getting around Rome.
I look forward to staying with Andrea again in the future.
