There's evidently demand to sustain such high prices.
"I'm booked for the entire Olympic period," said Marina Usher Mazur, who is renting her 3-bedroom second home in Notting Hill to two American families for 6,000 pounds ($9,550) a week. That's more than double her normal rate, but she still received more than 30 responses.
"I had a couple people say, you're crazy. But it went pretty easily," she said. "I was amazed at how many people were interested."
It's not impossible to find budget options, though, as long as visitors are prepared to commute. Kent and Essex, for example, are to the east in the Greater London area, and have good connections to the Olympic Park. Events will be taking part across all corners of the capital, so taking the time to research transport links will help determine which suburb to choose from.
"Many events are held outside east London," Roche said. "If you know where you're going, there's no need to stay in central London."
