This apartment is perfectly located; very close to Vatican City (you can see the St Peter from the terrace) and also the city center is not far away. Besides that, it has all you need: a washing machine, kitchen, shower, towels, et cetera. And a supermarket is only 50m away.
As other reviews already described: the room is indeed a bit noisy, but for us that was not too much of a problem. Only thing we would have liked is a bit more water pressure. The rest is all fine, we would definitely recommend this AirBnB as a base to explore Rome!
