Used this campsite whilst cycling the Danube route, and it was certainly one of the best equipped…read morewe stayed in; had a nice bar, several well kept showers, washing machines (although expensive at about 3EUR), and a helpful reception.
Klosterneuburg is a nice town, with a selection of decent restaurants and shops, although it is more convenient as a base for exploring Vienna - which is only around 12km away.
One warning, when we stayed here it was absolutely infested with mosquitoes (as was most of the Danube route) - so take some insect repellent!!
