The tour was very interesting, a different perspective on Pragues history, makes you look at the city in a different way. Stephan was knowledgeable and energetic, delivering his talk with humour. I would recommend.
The starting point was difficult to find. Look for the square near the Hard Rock Cafe just down from the famous clock, The No 2 is on a blue plaque and you walk up about 10 yards up the alley between two columns.
