Furious flathunter finds single mattress stuffed beneath stairs available for £500 per month

A woman was mortified when she went to view a cosy £500-per-month apartment - only to find it was a tiny cupboard under the stairs like Harry Potter.

Alex Lomax was stunned when the 'bedsit' she went to view turned out to be a slim mattress in a cloakroom under the stairs - with no window or bathroom.

The 23-year-old could not stop laughing when she realised the tiny accommodation in Clapham, south London, bore a striking resemblance to the cupboard under the stairs boy wizard Harry Potter was forced to inhabit by his cruel aunt and uncle.

The room lacked any utilities, but did come with a carton of Daz on the floor and coats hanging from hooks.
