NOTE: Our stay was over the Christmas holiday during winter.
Overall, great place. The best part is the neighborhood, especially via Urbana. But also having two amazing restaurants just a short walk away is great (Barzilai and Tre Scallini). Walking to the Roman Forum, Colosseum, via del Corso and more are all just 10-20 mins away. For large parties, the apartment is great. Three of the four bedrooms have their own bathroom while the fourth room has a dedicated bathroom across the hall.
There are some drawbacks but they weren't so serious that they detracted from our stay. While the place is clean, the tile on the floor is a bit old and has some stains and coloration from aging. A few details could be a little annoying: the light over the kitchen stove didn't work and shower pressure is low. But these were minor issues more than compensated for by having a great location and comfortable Roman base
