I took both the Power to the People tour and the Civil War tour. Both tours were extremely well organized and informative.
Almudena was great and tailored both tours to my knowledge level.
I knew nothing about the War of Independence, and so it was all new to me; and a lot to take in. Almudena made the history come to life and the walking tour went thorough parts of Madrid you would never see on a standard tour and gave me a glimpse of how and where the "regular" people lived and worked. There is a "well kept secret" church on the tour that was better than any other I saw in the city.
I knew a lot about the CIvil War, but Almudena took me to the places where things actually happened and it was amazing to see them and compare then to now. Due to politics, most of the sites are unmarked or have a very small plaque, but she knows them all.
Her grandparents fought on the Republican side during the war and the family stories made it all the more interesting. You might want to ask her about the Valley of the Fallen; you will get quite a response - I loved it.
