I have just moved from the main road in my neighbourhood (not a major road for the city, but busy for the area), where I was on the ground floor with a bus stop outside and apartment building entrances across the road and next door. Now, I'm on the top (5) floor, on a much quieter side road, and the different is astounding. I can actually sleep with the window open in hot weather.
