Police confirmed that they were called to the hotel over reports of assault last night.
She was arrested on suspicion of GBH and remains in custody at a north London police station.
The Metropolitan Police said in a statement: "Police in Enfield were called to a hotel in The Ridgeway, EN2 at 23:00hrs on Sunday, 2 July following reports of an assault.

"She has been taken to a north London police station for questioning.
"The victim was treated at the scene and did not attend hospital. Enquiries continue."
It is not believed that Stephanie and Jeremy's six-month-old son Caben-Albi was with the reality stars at the time.
Steph has been staying at the Royal Chace Hotel while she films relationship advice sections for Big Brother's Bit On The Side.
The former Hollyoaks star and Irish model Jeremy have been dating on and off since meeting on Celebrity Big Brother in January 2015.
After initially entering the house in a relationship with Sam Reece, Stephanie and Jez were inseperable when they left the house.
However, the couple had a number of messy splits, and were not together while Steph was pregnant with Caben-Albi.
McConnell initially denied that he was the baby's father, until a paternity test taken live on This Morning proved otherwise.
The 28-year-old has been living with Stephanie and Caben in Liverpool.
