Both the driver, Romeo, and the guide (whose name unfortunately I've forgotten) were excellent.
Romeo's driving was incredibly competent and the guide was personable, articulate, knowledgeable, and had a very good manner overall.
The local guide was also very articulate and well-informed and really gave us an understanding of the history of the area of the past 20 or so years.
There was sufficient free time to explore Mostar and, after wandering about in 46C heat, the air-conditioned coach was pure heaven.
Highly recommend the tour. Very well organised.
