Musicandyou.com has free and paid lessons. The free lessons are pretty good and include a detailed PDF of the lessons and audio. They focus mainly on blues and jazz piano.  The site can be a little bit fiddly to navigate around but there are some good lessons which include an audio description of how to play the tunes.

Below is a screenshot of a tune downloaded from the site in PDF format.
