If you have an old wooden floor with a keel, don't worry about disturbing people at all. If it's tiles and stone, you should consider it.
Wearing jogging shoes and training shoes with sheepskin soles will hardly make too much noise when practicing dancing. On the contrary, if there are high heels and wooden soles, there will be no movement downstairs and it is estimated that there will be movement next door.
Also, what kind of dance you dance is also related to whether you will disturb your neighbors. Except for a few kinds of street dances, all dances will not have a heavy feeling of landing. As long as the training method is proper, there will generally be no noise.
