Walking tours around Trencin?

After more than 15 years I am going back to Slovakia, and I am very excited. I lived there for a while when I was a child, but I am afraid that everything that I remember of had to change in the meantime. Since Trencin has special meaning for me, I intend to spend a few days there. What I would like to know is if walking tours around this city are still a good way of seeing it, so if there is anyone who could tell me that, I would be grateful.

To be honest, I was not aware that it is even an option. I mean, I was in Trencin a few weeks ago, and I did see most of the city on foot, but I did not know that there are walking tours that can be booked. In my opinion you do not have to book a tour, it is entirely possible to do it by yourself.
