"Our global PR agency in New York has already picked up on it. So we know that the news will travel fast. When people are thinking of travelling to this part of the world, they might put Queenstown on their list now ...particularly in the younger affluent demographic," Ms Poynder said.
Conde Nast Traveler said the Bishop's Suites - luxury stand-alone apartments attached to an 87-year-old Nelson homestead - had a "wedding album perfect" look.
"This gracious, secluded home feels like a country retreat, and being greeted like long-lost friends is just the beginning," it says.
"Mary and Peter Dallison may be new to luxury hosting, but what's here is on a par with the best high-end lodges in New Zealand."
Mr Dallison said the accolade was amazing, and would help to put Nelson on the map as a luxury destination.
"It just doesn't get any better."
