Difficult to call it enjoyable but it is well worth the experience lest we forget what humans can do to each other. My wife had serious misgivings about going but was glad she did although some of the sights were quite shocking and emotional.
Great experience. It was well worth having our own private transport as we could decide where we wanted to go and how much time spent at each attraction. Our guide Lucas was very well informed and great company, so much so that we bought him lunch in a proper and fantastic Polish restaurant called Dorothy's Kitchen.
