About
Description United Kingdom Sotheby’s International Realty is excited to present this historic four-bedroom apartment with two courtyard gardens in the heart of Mayfair.
Built in c.1762, the apartment is characterised by its abundance of period features; Mayfair cornicing accents the perimeter of the exceptionally high ceilings, and black American Walnut floors run underfoot, cleverly complementing the contemporary interior design.
The living spaces are particularly spacious and include a sumptuous formal dining room, a vast living room with floor-to-ceiling sash windows, and an eat-in kitchen, which opens to a courtyard.
The bedrooms are set on the lower floor, accessed by a beautiful glass staircase. Here, the ensuite master bedroom features a convenient walk-in wardrobe.
Three sets of French doors open to the courtyard and allow light to fill the room; there are three further bedrooms, two of which are ensuite. A handy utility room completes this floor.
Upper Grovsner Street is a fantastic location, perfect for Hyde Park, Grosvenor Square, or the private member's clubs on Mount Street.
There is a plethora of Michelin-starred restaurants on the doorstep, as well as unrivaled shopping. Set right in the heart of London, Mayfair is the epitome of luxury and exclusivity.
One of the most exclusive neighbourhoods in the city, the area has an array of high-end boutiques and lavish hotels.
