After that, it was "not my job to see where they were," he said.
One time, Giuffre brought her boyfriend into the house with her, he said, and Maxwell said the man needed to leave and wait in the car.
Alessi said he saw also "many, many, many" young adult female visitors, often lounging topless by the pool, who appeared to be in their late 20s.
He worked at Epstein's sprawling home from 1990 to 2002 — and admits he returned two years later to steal US$6300 in cash from Epstein's desk. He said Epstein confronted him about the theft and agreed not to press charges if Alessi repaid him, which Alessi said he did.
Epstein killed himself in jail in 2019, while charged with sex trafficking counts that alleged he abused dozens of underage girls in New York and Florida. The case against Maxwell stems from four now-adult women who said she helped him victimise them.
Giuffre's allegations, which include claims that Epstein and Maxwell trafficked her at age 17 and 18 to other prominent men who have denied it, are not part of the case.
Maxwell, 59, denies the allegations against her, and her lawyers say prosecutors are going after her because they can't try Epstein.
The Associated Press does not typically identify people who say they are victims of sexual assault unless they decide to tell their stories publicly, as Giuffre has done.
Maxwell, a British socialite, was Epstein's onetime girlfriend and, later, employee. Prosecutors said she took the girls on shopping trips and movie outings, talked to them about their lives and encouraged them to accept financial help from him.
The government also says she also helped to create a sexualised atmosphere by talking with the girls about sex and encouraging them to give Epstein massages, and the woman identified as "Jane" testified this week that she had sexual interactions with Epstein at age 14 with Maxwell in the room and sometimes participating. Maxwell's lawyers pointed to FBI documents that said the woman gave the government a different account in 2019; she questioned the documents' accuracy.
Alessi portrayed an imperious Maxwell letting it be known that she was "the lady of the house" and handing out a 58-page booklet with rules for staff on everything from how to address her and Epstein to what types of notepads to put on their desks.
"Checklists will assist you in making sure every task has been completed and not even the smallest detail has been overlooked," the book said, instructing employees to "try to anticipate" Epstein and Maxwell's needs and to "see nothing, hear nothing, say nothing" except when spoken to.
"I was supposed to be blind, deaf and dumb and say nothing of their lives," Alessi said.
Staffers had to "run the house like a five-star hotel," keep Epstein's cars washed and stocked with $100 bills in them for his weekend visits and avoid looking him in the eye. Maxwell said he didn't like such eye contact, according to Alessi, who said she and Epstein called him "John" instead of "Juan."
Earlier on Thursday, psychologist Lisa Rocchio testified that child sexual abusers often groom their victims in a progression that includes giving presents, building a sense of trust and gradually introducing more sexually charged talk and touching.
Before the trial, Maxwell's lawyers tried unsuccessfully to block Rocchio's testimony, saying it didn't have enough scientific grounding.
After she took the stand, defence lawyer Jeffrey Pagliuca suggested that some things she described as grooming — such as giving gifts, taking children to special places or paying them attention — could also be innocuous.
He recalled, for example, his grandfather taking him to the Bronx Zoo as a child.
"I'm assuming he wasn't taking you there for sexual abuse," she retorted, saying that simple kindness isn't grooming "in the context of a healthy and normal relationship."
