Great location when you walk out the door you can see the colosseum. It's about a 4 minute walk to the colosseum. From there, there is the metro line. Although I walked most places.
Maurizio was waiting for me when I arrived and showed me around the apartment and had guide books and WiFi information available.
Was great for me as a solo traveller to have a place to relax for an hour or two during the day and head out again in the evening. Would suit a couple also.
