When I visit N'berg, I used to stay exclusively at the charming, but somewhat ancient, Le Meridien Grand Hotel (or is it, Grand Hotel Le Meridien?)
After a disappointing and very much worn-out room at my last LM stay, during my subsequent visit to Nuremberg I tried out the Sheraton.
What I gave up in charm, I gained in functionality. Very nice room, terrific sauna, steam room, hot tub, and exercise facility on the top of the property (the LM has a random collection of exercise equipment in a dingy basement room) and everything was in tip-top condition.
The LM has old-world cachet with elegant public spaces, but the rooms are small and nothing special.
The Sheraton is a very nice property in a great location.
