Cultural Tip
In German‑speaking hotels and offices, rooms are usually numbered with three digits; the first digit often indicates the floor (e.g., 315 is on the third floor, room 15). Remember that ‘Zimmer’ is always capitalised because it is a noun, and the demonstrative ‘das’ refers to a neuter noun or a concept, not a specific gendered object.
