Can I stay in a hotel room without a house number?

You can't. A room without a house number in a hotel is a room that has not been decorated but has not been put into use, so it is not allowed to live. Hotels (also known as hotels, hotels, inns, guest houses, business trips, inns, hotels in China, and hotels in Malaysia and Singapore) are basically defined as business organizations that provide safe and comfortable spaces for users to have a short rest or sleep.
