For a small, localized area, a product containing chlorine bleach can be effective for non-porous surfaces like tiles and grout. Look for a thick, gel-based mold remover, such as HG Mould Spray or a similar product available at ACE Hardware or Waitrose, which will cling to vertical surfaces. However, these are only superficial solutions. The key is not just to kill the visible mold but to address the underlying moisture issue. Without improving ventilation and reducing humidity, the mold will return.

It is critical to note that if the black spots are widespread, have penetrated porous materials like drywall or the ceiling, or if you have any concerns about potential health effects, a professional inspection is strongly advised. DIY attempts on larger infestations can disturb spores and spread them throughout your apartment.
