It's located under the main road (before the entrance to an underground car park). We stumbled across it by accident and decided to go in and explore. This cost something like €3 each although there is a discount for students. It's a fairly small place (with no AC which means it got VERY hot and stuffy) it doesn't take long to go around but there's lots to see and lots of instruments you can play. We went after a couple of cocktails so it was a bit of tipsy fun and would probably be really well enjoyed by children and young families.
