The apartment is absolutely 5 star hotel quality. It was so clean, so modern, and so amazing. It's got history, but you don't have to feel like you're in year 1600 because it's redone.
The shower is heavenly, and I almost wanted to stay in it instead of going out to see Rome.
It's in a cute little neighborhood, there's a small market up the street and a few restaurants right on the same street. The colosseum is just a short walk away. It's probably not the most central place you can stay in Rome, but it's completely worth it to have such a nice place to come back to. The metro is right down the street, and there's a motorcycle rental shop just a short walk away.
I would absolutely recommend this place to anybody going to Roma, and it'll probably be the place I stay next time!
Oh, also- go have lunch or dinner at il Brigantino, literally you could probably jump out the window to get to it because it's so close!
