Landlords are openly offering women free rent in luxury properties in London in exchange for sexual favours.
The shocking adverts for tenants and roommates have been posted on classifieds website Craigslist.
The ads include one offering luxury accommodation in upmarket parts of the capital in exchange for "a 15 min adult cuddle once a week."
Journalist and author, Helen Croydon, discovered one of the ads online. She says it is one step further than prostitution.
