I also can't stand noise and in my case the solution was to find a two storey apartment at the top floors. They're fairly common in my city.

Another thing that happened by itself was my neighbour with whom I shared several walls moving out. His landlord put the apartment up for sale, but a year later there are still no takers.

I'm seriously considering buying it if only to keep it empty and my place peaceful.

Or buy it and be able to decide who the tenant is, instead of random strangers.
