It is located in a building with a museum-type area. The entrance is near to a (model?) tank and is near to the Mediterraneum.
It's marked as number nine with a picture of a bat on this map: http://www.zoochat.com/415/map-zoo-430249/

Oh, I must have missed this too - unless it is new?
It sounds like a very interesting exhibit, is it a re-purposed building (shelter or cellar or somehting?) or purpose built?
It was built as a shelter for general staff of nazi anti-aircraft protection force, with electricity, forced aircirculation, surgery room etc. At the end of WWII, Germans left it without fight. Then it was used to store potatoes and fruit. When zoo bought it, it was used to hibernate tortoises and cactus plants in winter. The current exhibit exists since 2012.
