It goes for £2000 a month ($2500) and is in Zone 1, a 25 minute stroll from the London Stock Exchange. You aren’t going homeless if you have £2000 a month to spend on rent, and Zone 2 is one stop away on the Jubilee line. You’re moving to Zone 2/3, or moving into a flatshare. Or out of London.
Given the location, pricing and finish I suspect it’s more likely to be used as a pied a terre – a second (weekday) home – for someone in the City.
