Convicted killer JORAN VAN DER SLOOT livin’ la vida incarceration!  

Serving a 28 yeqar sentence for murder, Joran van der Sloot is getting used to his new prison digs after begin transferred from the relative luxury of Castro Castro to the high security hell of Piedras Gordas prison.

"He is very happy where he is, everyone is very friendly there," his attorney Aldo Cotrina told

Joran who confessed to the May 2010 murder of 21-year-old student Stephany Flores in a Lima hotel room, was extremely depressed when he was sent to one of Peru's toughest penitentiaries after pleading guilyt in January.

"At the beginning, he found it hard as he was in solitary confinement for the first five days – there was no heat, no water, no bathroom; you get crazy down there as the conditions are hell," explained Cotrina. "Now he is in the general population and he has more friends and he is settling in."

In fact, the 24-year-old Dutchman is often the center of attention: "He is very popular there because he teaches English to the inmates, and he is very charismatic. He has a very good behavior record. He tries to help the other inmates because he has a superior education."

While Joran tries to settle into the place that could be his permanent residence for almost three decades, his attorney is campaigning on his behalf.

"The sentence of 28 years was excessive because according to the Peruvian penal law, Joran was only meant to get 15 to 17 years, so I am appealing to the supreme court to make a complaint to the Inter-American Commission of Human Rights," he explained.

"We are hoping to get it reduced by 10 years," said Cotrino, who also preparing a $50 million lawsuit on van der Sloot's behalf protesting the "excessive sentence."

Meanwhile, van der Slootremains the prime suspect in the disappearance of an Alabama teen while she was vacationing in Aruba. He was arrested twice in connection with her disappearance, but was never charged with any crime. The teen remains missing and has long been presumed dead.
