About
Detailed Description This beautifully designed 4,300 sqft apartment offers exceptional proportions, with impressive 4-metre ceilings throughout the ground floor that add to the sense of grandeur.
Rarely does a property of this scale and quality become available in Mayfair. The expansive living and entertaining areas rival those found in much larger homes.
The interior has been styled and finished to a high standard throughout.
Serviced by a lift, the apartment has been thoughtfully configured to maximise its entertaining potential, featuring integrated air conditioning, a modern sound system, and advanced security features.
The ground floor includes a spacious double reception room with a working gas fireplace, a sleek, fully equipped kitchen connected to a generous dining area, a separate study, and a guest cloakroom.
On the lower ground level, the impressive principal bedroom suite opens directly onto the main patio and features a large walk-in wardrobe and luxurious en suite.
This level also includes three additional bedrooms, three bathrooms, and access to a second, smaller patio area.
