Everything was really well organized, from the car to the driver, the guide, accomodation, etc...
AB Poland was quite proactive in engaging with me regularly prior the trip and prompt to provide feedback whenever required.
During the trip, the driver was very knowlegeable about things to see, where to stop, and the background / history of each sites.
We had also two guided tours (with the same guide from the national park) in the Bialowiesa Forest and in a early morning tour to observe Bisons. The guide was really really good. Extremely passionate about his work and to share info about the plant and animals. Thanks to his knowledge, we managed to spot roughly 60 bisons in total.
Finally the accomodation and restaurants picked by AB Poland were really great.
