I have stayed here before, and find the location nearly perfect. For a weary traveler arriving in Salzburg by train, it is only A5 minute walk. Check in is easy, and the amenities are adequate. The en-suite bathrooms were clean and well organized, separating the toilet completely from the shower area. Both areas were also very well maintained (I was placed in room 110).
I looked at the breakfast on offer, and while there was an adequate selection, I had breakfast after buying items are the SPAR Supermarket in Hbf Salzburg.
It was a very nice stay. I'll come again.
