Choose a spot where the ground is flat. The front wheel must be raised to the same height as the rear wheel. Either you have a ready-made block delivered with your trainer or you can make one yourself (with old books for example). The best way to reduce noise is to isolate your trainer from the ground, there are specific mats sold directly by specialty brands. If you don't have one, a gym mat or even cork coasters or trivets will do the trick.
