We thoroughly enjoyed our bus ride, never having visited Warsaw before. It helped us find our way round the city later and know what we were looking at. There did appear to be a problem with the route, with some diversion on that day which meant the commentary did not always coincide with the points of interest and it was difficult to follow ion the map . In fact there are 2 different routes , weekdays and weekends with different timetables so although it is convenient to book on line it is worth visiting Tourist Information before getting on the bus.
Undauntedly the best way to see Warsaw. Informative and fun. However can be difficult to find as the palace of culture and science is rather large. For those who might have similar difficulties finding the bus; it is in front of the Hard Rock Café.
Warsaw is a small city and this is a good way to see what needs to be seen. Very reasonably priced.
