We are a younger couple and we stayed here for 3 nights on our 3-week trip to Europe in July. We really enjoyed the location. It's in old town, next to several great restaurants and next to all of the main churches in Salzburg. The location is great.
The e-bikes we rented were also amazing! We loved that we could do that. It really made our stay so much enjoyable.
The breakfast was great, but there are only two workers and so the food seemed to always run out (though they would replenish it). There was always a line for coffee and it was a bit crowded. The spread was fantastic though.
The hotel has a nice spa, with sauna/massage/steam room but I don't think it's really "up and running" during the Summer season. It was deserted when I was there (I used the sauna) and it looked like it hadn't been used for months.
I think this hotel would be PERFECT if you are planning a ski/winter vacation in Salzburg, especially if you have a family (they have some cool loft rooms I saw), but for a young couple in the summer, it wasn't the best hotel choice for us. Rooms were nice and big, but the bed had a lip over it, so you couldn't sit up in bed, unless you had 2-3 pillows behind you. Yes, a small nitpick thing, but really annoying when you want to work on your computer/iPad in bed.
