Counter-Strike: Source Hint - Italian Closet Dweller
In the map cs_italy got to the apartments and there should be a (breakable) cabinet to hide in. To do this, go up the stack of logs by Counter-Terrorist spawn. Go through the window, up the flight of stairs (consisting of 4 steps) and into the next room. There you will see a large cabinet in the right hand corner of the room. Run and crouch jump into the cabinet. You will now be inside the of it. Although you cannot shoot out of the cabinet (it will break if you do) it is a good hiding spot.
