I live in a tiny place in San Francisco and have one pin - not against a shared wall and I will play late at night and haven't had problems. I'm on the third floor so it was a pain to get up the stairs but i also have hardwoods only but it's been fine. My building was built in 1906 too so it's not like it's well insulated for sounds (as any San Franciscan can tell you about places here in the city)
