Occasionally, I get an email asking for directions to my office. I always find this surprising, as my email signature or a google search will give you my address; and it should be a relatively straightforward task to locate me from there. This is for you who still have trouble.
At the University of Malta, shown in the below map (click to enlarge) go in the Pharmacy-side door of the Biomedical Sciences Building labelled 32. There is a lift on the right of the door as soon as you go in. Press 3 in the lift, or go up two floors via the stairs, and cross the corridor (your left) to the other side; to the highlighted white arrow below. My office is door no. 320. Knock and wait.
