We travel a lot and wouldn't normally go for a guided tour but needed help accessing some out-of-the-way hutongs as part of a research project. Stretch-a-leg were incredibly responsive and thoughtful, helping to tailor a walking tour that was exactly what we were looking for - and more. Our guide Tony was extremely knowledgable and interesting, but also unassuming and a pleasure to spend time with. Rather than him reciting information, the whole day was like a fascinating extended conversation which brought in local people we met along the way. We enjoyed it so much we booked another straight away. We wouldn't hesitate recommending Stretch-a-leg to anyone interested in really understanding Beijing - even people who wouldn't normally think of going on a tour.
