Private room for 1 or 2 people in an appartment with 3 roommates in the Historical Center of Genoa, in front of the aquarium. The neighborhood is pretty safe, and you can find plenty of shops of every kind and bars, restaurants, etc. The harbor, the buses (Caricamento) and the metro (San Giorgio or Darsena stations) are on your left when you get out of the building.
