Buyers who have seen the property have been "very impressed".
Luxury 411sq m pad with CV of $5 million-plushas views over harbour — even from elevator.
A luxurious penthouse apartment that is double the size of some houses is expected to sell for millions.
The 411sq m apartment has sweeping views of Auckland's harbour and has a 2011 valuation of $5,025,000.
Features of the three-bedroom apartment, which sits above the Stamford Plaza Hotel on Albert St, include 3.3m ceilings and a large kitchen with separate butler's pantry.
It is reached by a glass elevator which has its own harbour views, three carparks, as well as access to the hotel's five-star facilities such as room service and health club.
Gary Wallace of Bayleys, who is marketing the freehold apartment, said it was one of the best in the country.
"I think it is unique for Auckland ... the closest thing you could get to that type of property is the very high-end properties that have sold on the ridge of Remuera Rd but this is in the heart of down-town, on the doorstep of the waterfront. It is international, it is very, very special."
While a few apartments had sold for more than the penthouse is likely to fetch, Mr Wallace said it was in the upper price bracket for apartments. "It has a CV of $5.2 million, and I have had buyers there that are both local and international and have been very impressed."
It is for sale by negotiation. The sellers are based in Singapore, he said.
