AMSTERDAM — Federico D’Orazio is an Italian artist offering a unique service of a sexual sort in a part of the world famous for offering unique services of a sexual sort.So popular is his unique service that he’s offering a free night of it to the couple best able to explain what it wants to do with the opportunity if they win.

“I tried to make a space for real love in a city where sex is dominant,” he explains. “You can have sex, because it’s a safe structure.”

The “safe structure” in question is an Opel Kadett hatchback, seats removed and replaced by a double bed, then hoisted onto the top of 13-foot-high poles.

Although the novel love nest isn’t located near Amsterdam’s red light district, enough people have indicated an interest in trying it out that it could be used for at least six months, although D’Orazio appears prepared to stop receiving guests sometimes in mid-October.
