Semmering is the only ski/snowboard area within an hour's drive of Vienna. Also, it is VERY difficult to find on TripAdvisor the hotel's in the proper town right walking from the lifts. Panhaus I think is the only hotel that comes up as in Semmering but in fact thats a 20 minute walk from the lifts and there are many other places. Belvedere we booked no problem one day in advance, was family run by a nice Eastern European family, super simple cheap delicious meals, nice clean basic but very pleasant rooms. A bit on the cold side ... and you must not expect to receive sample shampoo soap, etc. But I really recommend for being close to the slopes - also great that its so close to Vienna but for sure not difficult skiing.
