Looking for a private car and driver to take us from Budapest to Zagreb in late April 2019. Does anyone have any recommendations? We wanted to take the train, but there is only one our day of travel and it is in the afternoon/evening.
There's also FlixBus - direct buses take about 4.5 hours. I'm not a big fan of buses myself, but in that case, perhaps I'd do it.
There is a comment in bus service here.
