You can practice anywhere that works for you!
Some people set up a specific spot in their living space with a cushion or chair, blankets, etc. Some people pick a spot outdoors surrounded by nature.
Other people practice in various locations depending on the type of practice they are doing and where they are. For instance, they may practice outside on grass for walking meditation, they may sit on a cushion indoors when practicing breath awareness, or they may be lying down in on a mat when practicing a body scan.
There is no right or wrong here. You practice where you feel comfortable.
Feel free to practice in different locations and notice what happens!
