I really enjoyed the tour, good information. Amazing views  (inside 😄), I can't describe it and the pictures don't do it any justice. The mine is absolutely amazing, the size, the beauty, the effort and detail on the handcrafted figures, everything really. Some of the rooms you enter are just jaw dropping, yout mind just goes to wonder how did someone build this.
The temperature is really nice inside, 14-17c at all times, I was happy in a t-shirt but some people had light jackets on.
There are loads of gift shops at the exit and they sell everything that the underground ones do, so unless you want to carry bags throughout the tour, buy your gifts at the exit.
I tried the restaurant before the return to the surface and it was great. Good food and good quantity.
I will be returning in the future.
For management, I just have two suggestions...One, please try to get some radio relays in the tunnels as the signal was very bad of you were in the back of the tour group. Two, bigger gaps between tours would be great, just to give more time to see some of the areas in more detail. But overall amazing.
