Cultural Tip
In German‑speaking hotels the abbreviation "Nr." (for "Nummer") is very common on signs and in spoken language. When speaking formally, you might say "Mein Zimmer hat die Nummer 305" or simply "Zimmer 305, bitte". In casual conversation, dropping the abbreviation and saying "Mein Zimmer ist 305" is also understood, but adding "Nr." sounds a bit more polished.
