Memory Palace (Memory of Loci Technique)

I have recently come across a memory retention technique referred to as the memory palace, also known as the memory of loci technique, whereby one makes connections between cognitive information and familiar physical spaces such as one's childhood bedroom. Is there any peer-reviewed research that suggests the memory of loci technique is beneficial, and have you tried this technique to memorize cognitive information? If you have, what has been your experience?
