Great location right on the main square in the Old Town.
Very comfortable mattress, nice and firm. Needs better pillows that actually support your head. Good bathroom, no leaking water onto the floor when showering that is otherwise so common at other hotels.
Two levels of breakfast available. I only tried the full buffet and that was good, although a bit pricey (12 euros per day). There is also a cheaper breakfast-to-go alternative, but I didn't try that one out. Since you're smack in the middle of town, you could of course just go out and have breakfast at some other place close by.
Since I was there during off season, the hotel was nice and cheap.
I would definitely consider staying here again if I come back to Nürnberg.
