Attended a conference in the city, so it wasn't a tourist trip. Hotel is hard-by a busy railway line, but with the windows shut there was no sound whatsoever from outside. With the windows open, however, it was loud! Not in a very glamorous setting but it suited my brief purpose. The room was very clean and comfortable - think Premier Inn, but smarter furnishings. Comfy bed, hot shower, food neither here nor there, just OK. You can walk into central Dresden with all the sights in a good 15 minutes.
It was so quiet in the corridors and at night that I thought the hotel must be empty. However, the breakfast sitting was packed out - this hotel has seriously good soundproofing! Nice not to have slamming doors and kids running down the corridors (or if they were, I didn't hear them!).
I would have appreciated more help with the dining room protocol....it wasn't clear whether you just found your own table, or had to wait. Felt like a lemon waiting for some guidance; always tricky when travelling solo.
