The Dorint is a chain of hotels originally from East Germany. It is 'old school', formal, but geared for the bus crowds, either pensioneers or sports teams, etc. The room was very comfortable. There was no internet for four days (!) which in 2019 is a tad hard to justify, but they made an effort in the lobby. The biggest issue is that you will walk an extra unnecessary 12 minutes from the Gewandhaus/Opera/start of old town for truly no reason when you can stay at the Radisson or Motel One which would be my suggestion. Bfast was very good but expensive at 17 euros. Just eat next door at the bakery or across the street. (The hotel falls right in between two tram stops so it is almost not worth it...)
