This was the tour I took from Vienna to Salzburg. The guide's explanations on the bus were very detailed (translated using a translation app). It was impressive how slowly and clearly they spoke, perhaps for non-English speaking passengers. First, we stopped at a small rural village, then spent about two hours in Hallstatt. Although it was a bit gloomy due to the rain, we still enjoyed the sightseeing. Upon arriving in Salzburg, we had a city tour (the guide changed to a local here; due to the rain, we didn't tour and instead picked up our luggage and went to our accommodation). There was a restroom and water on the bus, but it seemed unused. The driver loaded and unloaded all our luggage. It was a double-decker bus, but I was on the first floor, so I didn't see much of the scenery. However, there was a phone charger, so I was able to fully charge my phone (though some seats didn't have working chargers). Overall, it was a satisfying tour, combining sightseeing and arrival in Salzburg.
