We had a great week-long stay at this apartment in Rome. It's basically two blocks from the Colosseum and the Roman Forum, which is all really cool to be around at night.
The space itself was great; the bedroom is basically pitch black once you close all of the doors, and we really appreciated that as we were trying to properly catch up on sleep after a long flight. The apartment is at the back of the building, which makes it very quiet as well. We loved having an outdoor space for breakfast each morning and to relax after a day of touristing.
We really enjoy walking around new cities, so we loved this location because it's a decent (but not overly strenuous) walk to most of the tourist destinations, which means you get to see much more of the city on your way. It's also very close to the metro, which will take you to all of the tourist destinations as well if you don't want to walk.
We went out for dinner almost every night in the Monti area nearby and then hang out at the main piazza and get drinks from the bar on the square, which I highly recommend.
Great location and very responsive/attentive hosts.
