I've always lived in the countryside rurally and visited my sister in London when kids were small.
It's very different. In London things are immediately available and you get a choice. The down side is it's a city, it's busy, cars everywhere and rolling hills and fresh air are not in abundance.
We always enjoyed our city experiences and would stay weeks at a time so we got to do normal things rather than site-seeing. But I always wanted it to be a city break and then come back to my home in the countryside.
When my sister stayed with me she was always commenting on having to book and organise activities weeks ahead as there are fewer available. She said rurally she has to drive a minimum of 20 mins to get to anything, whereas in London you open your door and most things were available.
There are no takeaways that deliver!
But the plus side of living rurally is the countryside. No one. It's quiet, you listen to the birds, walk in the woods, play in the streams, throw stones in the sea. At night the sky is lit by stars because there's no street lights. Deer come up close to say hello. An abundance of wildlife are in my gardens.
I'm quite reclusive so it suits me well, but I know some people from big cites can struggle with the silence and lack of entertainment.
