A female friend accompanied her but soon left, according to her account in a complaint to the Russian Investigative Committee, seen as an equivalent of the FBI, Mailonline reports.
"Maradona shut the door, and first starting answering my questions and then began harassing me," she said.
He forced off her dress and she "managed to stop the harassment only when she was in her underwear", reported newspaper Komsomolskaya Pravda.
Maradona "even tried to take her dress off, and actually managed to do so."
She told her employers sm.news.ru: 'I got scared and threatened him I would call the police.
"In turn, he called the hotel security service.
"Three people carried me to the corridor.
"My belongings were left in the room.
"My phone was taken and not returned till three hours later."
She claimed that Maradona's "assistant came and threw $500 US dollars at me".
The journalist complained that she was forced to sit for three hours in only her underwear in the lobby of the five star hotel before her clothing was returned.
Local paper Komsomolskaya Pravda reported Employees of the hotel tried to kick her out but she insisted she would only leave with police, who arrived at 8am.
She said: "That is when I got my dress back.
"No one apologised.
"I am sorry that Maradona acted the way he did, it's not worthy of a man.
"What he did can be seen on the CCTV footage."
She said she was "stressed out" after the alleged bedroom incident.
Sources close to the retired footballer - seen by many as the greatest player ever - said the woman "got to his room and started undressing herself".
"Maradona didn't like it and asked her to leave," they said.
The hotel - which was not named - played down the problem to Russian newspapers, claiming the night was "quiet".
