The luxurious en suite bathroom is finished in marble and features twin vanity basins together with a bath and overhead shower. Two further double bedrooms, each with built-in storage, are served by an equally stylish shower room.

The principal reception room and kitchen enjoy delightful, elevated views across the beautifully maintained garden square, an exceptional green oasis in the heart of South Kensington. Reserved exclusively for residents[RW1.1], this communal area is landscaped with lawns, mature trees and established planting, providing a charming, leafy sanctuary in one of London's most distinguished neighbourhoods.

Onslow Gardens is one of South Kensington's most prestigious and sought-after addresses, perfectly positioned to enjoy the area's outstanding selection of boutiques, cafés, acclaimed restaurants and cultural attractions.
