We were only at this property for one night, but I was very impressed with the accommodations. You couldn't ask for a better location in Salzburg. All the points of interest are mostly right outside of the hotel.
I'm not familiar with this particular chain of hotels. I found it a little odd, though, that guests are given a, sort of, housekeeping list. It's mostly to clean up after yourself and take your trash to the basement receptacles. Not a big deal. I try not to make a mess anyway. Just thought it was a bit odd.
Having said that, don't hesitate to book this hotel. It's very nice and clean. The staff are super friendly and the location is outstanding!
