You don't need to use blocks: You can create a view with a page and an attachment. First from admin/structure/views/add, you create a view for content, selecting the content type to show and selecting Create a page.
Click on Save and edit.
On the next page, which shows the view settings, click on the + Add button and select Attachment.
The next page will show the settings for the attachment.
The attachment shows nodes for the same content type the Page view does. The first step is changing that. Click on the Content: Content type in the filtering criteria.
On the top, change For from All displays to This attachment (override), select the content type to show. Click on Apply (this display).
The attachment still need to be attached to the Page view. On Attach to: Not defined click on Not defined.
On the dialog box, select Page and click on Apply.
If you want the attachment to appear after the main content, change from Attachment position: Before to Attachment position: After*. Then, click on Save to save the settings.
The view needs to be styled better (for example, selecting Grid as format instead of Unformatted list), but it shows two different content types on the same page.
