I will let IMDB speak for me on this.

Room in Rome is a movie starring Elena Anaya, Natasha Yarovenko, and Enrico Lo Verso. A hotel room in the center of Rome serves as the setting for two young and recently acquainted women to have a physical adventure that touches their very souls.
One of the memorable exchanges:

"You owe me."

"The truth or a lie?"

This is a superb movie. A person has to pay attention to the stories that are told by the women. Which is real and which is made up because of a desire to avoid full disclosure?
