Does "location" have the same meaning as "place"?

I wonder if "location" and "place" can be interchangeably used?

Where is the best place to place a piano in a house?

Where is the best location to place a piano in a house?

"location" seems to me that it implies bigger places such as a building, house, island.

Am I wrong?

Your question focuses on the nouns location and place. It seems awkward to query for location within a small area such as a house. Location stems from the verb to locate, "to establish oneself or one's business," which implies a larger areal context. Someone later seeking the location of the piano approaches the question from a context more like "where in town is the piano?" whereas someone who knows a priori the piano can be found in the house would ask simply "where is the piano?" I will concede though that asking "in what place is the piano" goes further afield, inquiring about the name of the town. So, I don't find the two terms to be completely interchangeable, but only on the basis of current conventions. Perhaps the best way to state this would be "Where is the best place to put a piano in a house" (but now the discussion shifts to put vs. to place).
