fungus farm 

Accommodation typically offered by cowboy landlords and especially to students, shot through with a fungal growth. The fungal infestation is often temporarily retarded at point of sale by gas or electric heaters which the landlord has removed shortly thereafter. Even if the hyphae have ramified all the way into or up from the foundations, in popular mythology it is always the tenant's fault.

Shane and myself got a cheap ground floor apartment ostensibly for a year on coming to Cork, but it turned out to be a fungus farm and we had to move out after a month for the good of our health.
