US President Donald Trump and North Korean leader Kim Jong-un meeting is expected to be at the Santosa island in Singapore.
The much-anticipated historic summit is scheduled to take place on 12 June, but many details are still unconfirmed.
It will be the first meeting between a North Korean leader and a sitting US president.
Trump said on Tuesday that plans were "moving along very nicely".
"A lot of relationships being built, a lot of negotiations going on before the trip," he told reporters.
"It's very important - it'll be a very important couple of days."
White House press secretary Sarah Sanders confirmed on Twitter that the summit would take place at the five-star Capella Hotel.
The 500-hectare island, only a short distance from the main island, is home to luxury resorts, private marinas and plush golf clubs.
But the island also has a dark history of piracy, bloodshed and war. BBC
