We took the 2 room apartment with a good sized balcony. It was very clean, and the house was beautifully landscaped and had comfortable modern furnishings. We got in a bit late, and as promised the landlady left the key in a combination box for us.
To get to the house, you have to take the footbridge over the tracks at the station. We had a bit of trouble figuring this out because the bridge didn't go all the way to platform 1 where our train came in, and we didn't see the bridge. It looks like it will go to all platforms soon, but even when we went to 3, we couldn't see it at first because of a blocked view. Once we found our way it was an easy walk. But, it's a good 20 minute or more walk to all of Salzburg's attractions, and there weren't many restaurants around that we found. Still, we liked the neighborhood, quiet, mixed residential and some commercial.
Breakfast was ok, but unless you really like the Euro breakfast of meats and cheeses and bread, it's not worth the 8 Euro apiece in my opinion, especially since there's a small Norma grocery store almost next door, open at 0800, until 1900, I think.
We barely saw the landlady or staff except for the first morning's breakfast, which is when we paid and check out after the 3rd night when we saw her in the hall and she said to just leave the key in the door. I'm not sure whether there was even a common room like you'd expect in a B&B like place, but our room was so comfy we were fine.
