She was a mother of three, Scotland Yard said.
He will appear at crown court later this month.
Detectives say it could take a week to identify the clothed bodies.
It will take days to identify the victims, police have said.
A second man arrested on suspicion of murder remains in police custody.
Police are working to identify the women.
This is Frank Buglioni, the 23-year-old north Londoner and super middleweight fighter training out of the TRAD TKO Boxing Gym in Canning Town. It's a professional gym, so it's all business as fighters hone their bodies into liquid iron.
