Although Brač Airport is a transport airport, it is also very
friendly for small aircraft. You will get aviation fuel here and
they may even allow you to bring fuel from the gas station to the
plane if you want to put it in your Rotax rather than Avgas. The
fees are very reasonable and the handling agent even sang the
Croatian national song as a welcome when I arrived here. You can
get to the city by taxi and often by bus. But it needs to be
checked.
