We stayed there last fall and it's a nice hotel with an ample breakfast buffet. The location is on Piazza St. Antonio which is the bus stop so you couldn't get closer to public transit. They have a jacuzzi out on their deck that appeared out of service but then our last nite we found out you just have to ask them to turn it on.
However if I was staying in Ortisei again I'd look for a place with half board instead. There is a restaurant immediately adjacent to Garni Snaltnerhof and there are a few others in town; a couple of pricy ones and the rest more towards the casual range. I think we would have eaten better dinners staying at a place that took pride in preparing regional cuisine. Just my opinion.
