About half of his Burton Way renters have other addresses outside the city or even outside the country, he said, often using their apartments as an alternative to staying in a hotel. Full-time residents include doctors who work at nearby Cedars-Sinai Medical Center, bankers and entertainment executives.

Residents in upscale units like the Penthouses at Palazzo also tend to be single, broker Umansky said.
"They might be going through a change in life such as a divorce; making money or losing money, but they want to rent something really nice."

"This is all about an urban lifestyle," Umansky said. "You won't see luxury apartments up on Mulholland Drive."
