We found this two-story apartment to be very clean, well stocked with soap, toilet paper and shampoo, and to have everything we needed during a 10 day stay. Beds were clean and nicely equipped with plenty of blankets for our January visit (temps hovering around 5C/40F). It’s not a large space by US standards but was plenty for the two of us and would probably be fine for up to four. Remember the place was built long, long ago when folks were much shorter, and watch your head as you pass under the original ceiling beams if you’re over 6 ft. We really enjoyed our time here.
In terms of location, there’s a grocery store called “Express” about 60 seconds walk to the left, there’s an excellent breakfast cafe 20 seconds walk to the right, and easy walking distance to the Vatican, Colosseum, Roman Forum, Theater of Apollo, Museo Centro... if you’re willing to walk 20 minutes you can see masses of historical sites as well as tons of shopping, plazas, markets and restaurants within that 20 minute radius. We used Uber for more distant locations with no problem.
