So, what could I reasonably expect for £650 per month in London?
A double room in a not completely crap share house, in zone 2/3. with a washing machine in the kitchen......
or a bedsit of quadruple this size, in a vaguely crappy area (or indeed the area this one is in).
I earned pittance for many years, as did many of my friends, and certainly nobody ever ended up in a place like this. The closest I saw to this was a bedsit more than twice this big, but that was right off Hyde Park in Zone 1. And about the same price
This is just a crappy landlord hoping for just one poor newbie to London to take their word for it that this is all they can afford....
