Google Maps is the best service to find yourself on the streets of any city in the world without leaving your home and arrange a virtual tour anywhere in the world.
When I want to travel, but for some reason I can’t do it, I just open Google maps and turn on the street view mode ( to do this, hold down the yellow man in the lower right corner in the google map with the left mouse button) .
Streets and roads are highlighted on the map, along which you can arrange a virtual walk ( for example, in Europe, these are almost sections of the map) .
