Structure of the table at the same data?

Question

Software design

Good morning.
The next question, I sit, I think whether it is necessary to invent.
There is a table containing information about the object. And there is a complete set of data of the same type, for example, as properties here: https://www.airbnb.ru/rooms/432044?s=QQulq1Q8&chec...
How should data be stored?
1) In the same table
2) In a separate table.

Answer 1

It is a rare case when the data is immediately presented in almost normal form , therefore it fits perfectly into one database table.
Only fields with an enumerated type (for example, you have "Placement Type"), of course, need to be made keys to external tables (well, this is obvious).
The only exception is that "Sleepers" must go in a separate table and be connected to the main table as Many-to-One, since their number is variable, and they themselves represent a separate data type. Well, comments (if you keep them), then, obviously, they will go through Many-to-one.
