Google maps is the best invention google has done. They have taken the pain to actually cover each and every part of the world and place it properly and exactly on the map.
The locations and the distance is accurate and u can assume about it by the fact that a zoomed in view actually shows u the exact shape of the building and not just a rectangular block. It shows the shortest distance between two points and considers the traffic restrictions in ur city too.
No matter where u wanna go, just google map it and u will reach there on time without any hustle bustle.
