“Cold rent” (Kaltmiete) is the base monthly rent, covering only the living space. “Warm rent” (Warmmiete) includes utilities like heating and water, making it the monthly total you’ll pay. Keep in mind, utilities (Nebenkosten) are recalculated annually based on your usage, so costs may vary. Some landlords offer all-inclusive setups, often in coliving or serviced apartments, which can include extras like Wi-Fi, furnishings, and shared activities.
