4.5 stars, Highly recommended for one night, for novelty! The only issue is the showers, it is a fun novelty once but not suitable for a long stay. There is nowhere to put your clothes when you shower, and they are mixed gender bathrooms, so don't stay here if you are concerned about bathroom privacy. The showers are also only slightly warm. This is all part of the experience! Just be mentally prepared.
Aside from this, I found the military-style mattress with sleeping bag actually very comfortable, I had a very good sleep. It is cold inside the bunkers and no heating available, be prepared for that with layers. The museum part of the bunker was very cool to look through.
Breakfast is a small, simple buffet where you can make your own chlebičky, toast, granola, and tea/coffee, with some fresh fruit. I also enjoyed this part of the experience.
Overall I highly rate this as a cool, different experience in Brno!
