The location of the hotel is not very convenient. In general, there is not much you can do in the town of Leoben and there is not much you can do in the area either...
The Asia Spa was nice but unless you want to have some water adventure, you have to make sure you go to the "Spa" part rather than the general swimming-pool-area (it can get really noisy there since it is open to the public at large, i.e. it is not the best place to take your afternoon nap). On the other hand, the "real" Spa part was ok - kids under the age of 16 are not even allowed in... it is really calm and relaxing in the Spa area. However, do not be surprised if you happen to see naked people around in the Spa area (it is not obligatory to be naked but most people were naked at the time of our visit). This includes naked people in the pools (i.e. not in the saunas only). I have to say that in general I had a good impression about the level of hygiene in the Spa area.
I was not to keen on the bed and the pillows in the room. Although there was a notice in the room saying that one could request extra pillows, I think that the "basic" pillow should be of good quality too (without having to request the "extra" ones).
Many of the staff were not able to or were not really willing to communicate in English. Nevertheless, this is something I have experienced in many Austrian hotels.
As to the receptionists, one could see it is not their dream job. The services provided by them were ok but with the exception of one lady, one could see it was "simply their job" (no extra smile or anything like that).
What I liked about the hotel, was its modern touch, new furniture and fittings in the room. I also liked the fact that the common-areas (the lobby, the restaurant etc) were really spacious and open. In general, the interior of the hotel was really nice (as to the exterior, I would say it is more functional and nice but this is not a major issue, I suppose).
The food was also nice (although I prefer buffet-style dinners to "choose-your-meal-from-the-given-options" style). You had the possibility to choose from 3 or 4 main courses. Of course, there was a starter, some soup, a salad bar where you could mix your own salad, then you had the main course (of your choice) and a dessert (not multiple choice :), one choice only) to conclude your culinary experience. As suggested above, the food was nice but it was not something that I consider to be the "pulling element" of the hotel.
Overall, I think it is a good hotel for business people and it could be a good hotel for those who like spending much time in wellness.
