Old furniture is usually from rather high class households and thus often made for large rooms. In a regular apartment, you can't really use much of that. My great grandma had a bunch of these pieces, often older than her. But they take up tons of space that most people simply don't have. And the fact that they're usually pretty dark doesn't help.
You can get a piece or two as a highlight, but not more.
