1. Open Office
2. Libre Office
3. Kingsoft Office.
The above three options are the best alternatives. Open Office and Libre Office has alternatives for Word, Excel, PowerPoint and Access also but Kingsoft Office has alternatives for Word, Excel and PowerPoint only. Kingsoft Office are very similar to Microsoft Office interfaces.
If you don't want Access I strictly recommend that King Soft Office as the best alternative for you.
Enjoy with open source software.
