Nenad is a true gem of a human being. Here is what I liked:
1. Nenad is communicative and kind. I got lost (took the wrong bus) and he was able to fit me in on a tour he was giving later. He did not have to do this, he was just nice.
2. This was the opposite of an overly touristic cruise. It was like being on a friend's small boat. He had beer, wine, a few snacks, good music and conversation.
3. He was able to chat about history, politics, family, fun stuff - very very good English.
4. The starting place in Ada Ciganlija is easy to reach by free public transit (if you take the correct bus lol) and the park is nice to walk around.
