Our stay at the hotel was very comfortable. We had a standard room and it was spacious, with two large twin beds and a large bathroom as well. It was clean and aside from no coffee machine or kettle, it had every amenity you could want (wifi, large television, locked safe, etc). The staff was very helpful and accommodating. At the last minute, our stay had to be shortened by one day and the manager was very quick in assisting us with this change to our reservation.
Our only word of caution to travellers would be that this hotel is situated a bit outside of Linz - about a 15 minute walk from the central station, and 15 minutes to walk into the city centre.
