I was already wondering, where that Lynchplatz might be, in German that sounds more like "square where executions happen" :-D
If you are at Lendplatz, its really just a short walk to the city center, no matter where exactly you are. The reason why the area is so trending is that on Lendplatz itself, there is a market in the morning, where farmers sell their products and after they leave, parts of the area has caffees with big outside sitting areas, in summer sometimes with small scaled live music as well. North of it there is a restaurant called "Wildmoser", that also has a nice outside area under shady trees. Going south, several rather "hip" bars are located.
To be honest, it is not too special in my opinion, but as it used to be some kind of (very small) red light disctrict centuries ago, some people might feel a different vibe there
