We stayed for 3 nights and had a better than average stay. If you've read that the location is a bit of a distance from the train station, you've read right but it wasn't too bad. I didn't seem so far when mapped it on Google but since the Salzburg train station is in the middle of construction, there is on a few exits to get on the correct side of the tracks and dragging luggage from the train to the hotel was a huge pain for us.
Overall our stay was pleasant. The room was very comfortable, modern, and clean. The rooms have dark wood flooring and had lots of space. Our room even had a small loveseat couch that pulled out to a twin size bed if we needed it. Bathrooms were clean and there was tons of space by the doorways for luggage and storage.
However, location was pretty good. One street over running parallel to the mountain, is mostly pedestrian with tons of little cafes, shops, and restaurants. The hotel is about a 5 minute walk to Mirabell Palace and about a 10-15 minute walk to the city center.
Staff was kind of unpleasant. Not terribly rude but not very helpful either. They acted as if they had better things to do and didn't want to bother with customers. This was pretty much my only gripe about the hotel. If somehow they could improve the staff's attitude, it would be a great hotel!
