Giuliano is a great host, he was there waiting for me when I reached. The apartment is located 10 mins walk away from St. Pietro train station, and the Vatican Museum entrance is also 15 mins walk away.
You’ll need 30 mins to go to the center if you use bus, and 15 mins by taxi. The apartment is old, but clean. There’s pretty much all the necessary things you’d need to have a peaceful stay.
The road outside the apartment is pretty busy so you can expect some traffic noise, but it didn’t bother me once I closed the windows. Giuliano had also arranged for some snacks as a complimentary welcome gift.
All in all, I had a great time in Rome!
