The apartment is nice for 2 persons and well equipped. It's located close to the Vatican which is great for going there but for the rest of the sights you have to walk for a longer distance or use the metro. Metro station is close by so this made it easy to go around the city.
The apartment is next to a roundabout and the traffic can be loud at night - but I assume this is everywhere in Rome. Even with the windows closed it can be loud.
There's a 24/7 supermarket just across the street which comes in very handy.
Loredana was very helpful with our requests and individual check-in/out times. She is easy to reach and replies quickly.
