It’s a great option to stay near the Vatican! It was easy for us to get there by walking or with a short walk you can get to the Gregorio bus station, or the St Pietro train station.
The apartment is just how it looks in the pictures, I would say that even better!
Just take into consideration that to the get to the apartment there are some street stairs, just in case you are bringing with you a lot of luggage or a baby stroller like we did.
