★★★★★
Most amazing experience I’ve had yet. The Bunker is preserved to the smallest detail, with original furniture, items, as well as working air condition from the 70s.

Amazing visit to Tito’s Bunker! A fascinating journey into history, made even better by our wonderful guide Layla, whose knowledge and enthusiasm brought the place to life. Highly recommended!
★★★★★
It is something really worth to visit. … Everything is made to be used, working and in condition as it was when it was built. Impressive equipment, long corridors - very nice ambiance.
★★★★☆
The guided tour of the bunker was very interesting. The staff were all very friendly, welcoming, and incredibly nice. … This place is definitely worth visiting if you are in the area.
