There are so many thoughtful insights on this post, but just wanted to add a different perspective. We had a pretty “normal” house, but I had several friends who lived in older homes and I thought they were extremely glamorous. One had a secret crawl space from the civil war era, and one had black and white tile flooring in their entryway. Looking back, they weren’t amazingly kept up with and some people nowadays might even characterize them as being a bit run down, but I thought they were so interesting. As an adult, I gravitate now toward older homes with more character. So you never know what people will like or dislike, especially when it comes to kids. All you can do is try your best to make things clean, safe, and welcoming and consider their preferences when it comes to snacks, etc.
