Skopje is doubtless a place to visit and I think the tour is well-organised.
However, our experience was a bit disappointing because of our guides.
Our Bulgarian guide driving was, sometimes, quite risky: overtaking near bends without clear visibility, accelerating too much within Sofia and speeding.
Our North Macedonian guide was all over the place and also his explanations were. It was hard to understand him, we didn't learn much about the country and we were left in a museum when we told him we didn't really want to see it as we have little time to do some souvenir shopping.
Also, the Bulgarian guide didn't know who the local guide was. I think this is something the company should know in advance.
The price of this tour is unbelievably expensive for what you get.
The idea of the tour is great but I guess we were not lucky with the guides and price is too high.
