A 72 sq/ft one bedroom flat is being advertised as a "smartly arranged studio apartment" and rented for over £46,000 per year.
It is thought to be the smallest flat on the property market in Britain but costs the same as a seven-bedroom Grade I Listed country home in Somerset, once owned by Henry VIII.
The flat at 82 Brompton Road, Knightsbridge in south west London is part of the Princes Court luxury apartment block.
A three bedroom flat in the complex costs £2.5m.
The apartments sit directly facing Harrods department store in one of the capital’s most expensive retail areas.
Television and 'clever' space for a single bed
Kitchen unit is enclosed behind a sliding mirror door
Narrow toilet and shower suite
Marble-floored lobby of Princes Court
The tiny flat's kitchen facilities are concealed in a cupboard behind a mirror door and consist of a microwave, sink, hob and mini fridge.
The bedroom allows for one single bed with a television overhead. The toilet and shower are in a separate, extremely narrow room.
Ed Woolgar, lettings director at Harrods Estates, said: "Its compact but clever design means that the tenant has everything they need including a hidden kitchen, complete with fridge, microwave, hob and sink, along with a bathroom with shower, basin and WC. There is enough space for a single bed and the TV is perfectly positioned for relaxing evenings in."
