How many kinds of hotel rooms are there? What's the difference between a double room and a standard room?

The double rooms in hotels and hotels with the same scale and spatial structure refer to the double bathroom rooms in three-star to five-star hotels, and the double bathroom rooms in each hotel must reach more than 75%. There are two beds in the room, and the accommodation guide is on the table. There should be central air conditioning, refrigerator, desk lamp, floor lamp, sofa chair, kitchen utensils for putting quilts and clothes for guests. The toilet must have a toilet, a big bathtub, a shower head, a washbasin, a bath towel, a towel, a comb, disposable toothpaste and a toothbrush. This kind of room is called "standard room", also called "double independent standard room".

A double room is a room with two beds, which may or may not have a bathroom, hot water and so on.
