I've stayed here a few times in the past few months. It's a pretty standard aloft, but they have been good at (proactively) upgrading me to their 30sqm-ish "suite" -- just a room at the end of the corridor, with a little bit of extra space and a small couch. I find the breakfast pretty good for this type of hotel (breads, fruit, muesli, some cold cuts, scrambled and hard boiled eggs, Nuremberg sausages). IMO, the award categorization (Cat 4) is outrageous, but there have been some BRG opportunities here in the low 60 Euro range, which makes this hotel a stellar deal. When staying in Stuttgart on points or if rates are close to the LM, by all means pick the LM -- much better!
