On my first night in Madrid, I went on the Spanish Inquisition Tour by Sandemans. What can I say? I am a sucker for walking tours. This is a daily tour available at 19h00 from Plaza Mayor. My tour guide was a lovely British girl, Lexi. The tour lasts about 3 hours and a walk around Opera, Callao and Santo Domingo. Please note that although it is advertised in the “free tour” pamphlet, this is NOT a free tour. This tour has a flat rate.
