"At someone's place" vs. "at someone's house" vs. "at someone's"

Question

Do the three phrases convey the same meaning when we're referring to the place where one lives?

Answer 1

As long as the context is clear, then yes. But context is very important.

Examples where they would not have the same meaning:

• Names of bars, clubs, etc. "We're heading down to O'Connelly's tonight; care to join?" or "They met at Meg's."

• Or basically any other kind of proper noun.

Again, if the context makes it clear that we're talking about residences, you're golden.

Answer 2

The three all convey the same message, but I've always felt strange referring to someone's "house" if it is not in fact a house, but rather an apartment or condominium.
