29.2.25? 
what is this code?

   ​At UAveiro, spaces are identified by the numerical sequence "building . floor . room". If you find the designation "29.2.25", for example, you will have to go to building 29 ​(Technology Laboratory Complex), go up to the 2nd floor and look for room 25.

   You can also ask anybody in the building for "Aquário", and they will point it to you.
