If taking public transport make sure you take the train not the metro to the Roma san Pietro station.
Also, it is cold in the apartment at night.
There was never hot water in the shower so plan accordingly.
This is not the spot for a relaxing stay. The apartment building is very noisy. You can hear everything, the good and the bad :/
But if you are a solo traveler just in Rome to explore and be out it’s fine.
Also the pillows do not have changeable cases so you might want to bring your own.
