Kacbu lists 1 Washer-Dryers that stands out for Apartments: Haier. This is not a ranking; the product is here because its editorial assessment found it strong for this use.
In an apartment two things matter: the noise on spin and the depth of the cabinet. The EU label states spin noise in dB and gives it a class; on a machine against a neighbour's wall that figure should be low. A shallow cabinet also fits a narrow bathroom.
