I'm curious - why would you not want elderly neighbours?

[Herald_MJ]

Actually, I don't think any of those criteria should definitively rule a place out.

[smcl]

Personally me neither but I can understand the other reasons to some extent

Because some are difficult - for example being nosy, over-sensitive to noise and so on.

Everyone can be difficult - I rented a room in London where the guy below us had a habit of playing shooter games on his home cinema system around 10-11 pm. During those hours, it felt like living in the warzone (constant loud explosions, shooting etc.)

That is true, but I found out that issues with living among elderly neighbours are much more troubling. So I would like to filter that out if I was ever to look for a flat again.
