Roboto Slab

Roboto Slab is a serif typeface designed by Christian Robertson, added to Google Fonts in 2013. It's available in 9 weights, as a variable font.

This is one of 7 character sets supported (cyrillic, cyrillic-ext, greek, greek-ext, latin, latin-ext, vietnamese). Being free and open source, it's a great choice for web projects, print, and branding — and it's a frequent result in the font finder.
