The guides Danuel and Jaime were very professional, nice and friendly. The tour to the camp was very moving and Potsdam is beautiful. The bus was comfortable and the time table was kept very well. The only problem was that we booked a tour in English, and only when we arrived to the meeting point we learned thst is was canceled.The guides were very helpful. At the camp we were with Daniel who spoke in Eglish but we had to leave before the end of the tour,to join Jaime's group to Potsdam, a tour that was in Spanish. As not Spanish speakers, we barely understood... Still it is very important to thank Daniel and Jaime for their help and effort
