Visit or not visit?

Sorry if this is another ‘should I’ post, but I wanted to get a recent locals perspective. I was planning a city break to Frankfurt in January with my wife, just a Saturday to Sunday (we’re from London). I last visited Frankfurt for work in 2017 and it was great. But after much reading I’m second guessing a trip. We were looking at staying in Innenstadt, getting a train in from the airport and enjoying a night out. But a lot of posts make it sound like the city has taken a dive in recent years and there’s loads of central places to avoid. Am I overthinking it? Vielen Dank!

Edit: Solved! Thanks for the input. I had a moment of low confidence, but we travel all over and I’m sure it’ll be great!
