Hello, if you´re interested in sensibly priced but high-quality tours in Prague (and outside), I can recommend http://www.caputregni.cz/about.html Myself as an experienced traveller in Prague went on to a tailored tour in Karlin and Zizkov and was amazed of the knowledge of history and personal touch of the guide! The guide is extremely enthusiastic about her job, this is the main difference to most of the competitors.
