According to new tenant Patricia Croland, the previous occupant of Apt. 12C at 208 Hill Street was clearly not the least bit bothered by mildew. 'Wow,' said Croland, who moved into the apartment Monday. 'Somebody out there obviously doesn't have a problem with thick layers of white fungus.' Among other things that apparently did not disturb the previous tenant: large black stains on carpets, painted-shut windows, pubic hairs on doorknobs, and overpowering rotting-bologna stenches in refrigerators.
