According to Lt. Robert Grady, a male and female walked into the lobby of the inn at 738 Boston Post Road arguing over personal property.
Neither was registered as a guest.
After responding officers completed an investigation, Carrissa Wilson, 22, of 655 Boston Post Road, Apt. 1103, was arrested and charged with domestic assault and battery.
Grady said Wilson allegedly slapped her boyfriend across his face.
Wilson was bailed out and scheduled to be arraigned at Framingham District Court.
