You want simple google map without some extra modules, API keys etc? This is rather simple, all you need is to go to google maps, choose your location and go to upper right corner where is "Paste HTML to embed in website" code, copy that code. Go to Block sections in your drupal administration, create new block and place that code in block. Use Full HTML input format so all html can pass and there you go, you will have a block with a map. You can edit width and hight in code, edit lable below it and customize it to your needs. Same way you can do with all other maps like BING etc.
