Best Free Alternative to Squarespace

I'm building a blog and I want it to look Minimally Minimal-esque. So the front page only displays the latest post, you've got a toolbar and all the widgets and navigation stuff is either at the top or at the bottom (no sidebars either to prevent distraction).

I tried Squarespace and I really liked it, but sadly I didn't want to pay for what is more akin to a personal blog than to a professional one. After that, I've tried Weebly, Tumblr, Strikingly, Wordpress, Blogger, Wix but none of them could serve my needs.

Does anyone know of a better blog-hosting website (I don't want to spend time to code my own website)? Or are there free themes in the blog hosters mentioned above that I've missed? Thanks!
