The only bad thing about them is that they tend not to be accessible for people who have difficulty climbing steps... which is fine as long as there's lots more available housing which is accessible. I lived in an apartment over a specialty supply company one summer; it was a great bicycle commute to work, walking distance to a supermarket, and nobody was actually in the ground floor at the times I was home, so they certainly didn't care if I played music loudly or thumped furniture across the floor.
