Burned a few of my remaining 7-night travel package certs here -- with rates often exceeding €150-200, this is an excellent place to redeem these, although Stuttgart perhaps isn't a 7-night city unless you have work/friends/family here.
In contrast to a number of middling stays I had here over the past decade, this hotel has improved. Front desk staff are friendly and pleasant to deal with, refurbished rooms are pretty good, and breakfast is relatively strong by Covid standards (with the buffet pretty much back to normal at this point). I was upgraded to junior suites on several stays, but with occupancy picking up, it's becoming less likely, especially for longer stays -- lots of business travelers here during the week, and weekends were crazy busy with people apparently paying for these suites. Still, the remodeled executive chic whatever rooms are quite nice, albeit not very large. Only caveat is that an ungodly number of rooms have connecting doors, and I've heard a lot of crying babies, rebellious teenagers, noisy TVs, and so forth in adjacent rooms.
The main station construction is still going strong, and although the path from the current temporary main station tracks hasn't changed in a couple years, the path from the hotel toward downtown changes every few months. Important to note that the U-Bahn station has been relocated closer to the main station, so arriving by U-Bahn, too, now requires crossing the pedestrian bridge across the busy thoroughfare. Access to the hotel can thus be challenging for anyone traveling with lots of luggage, and someone with a mobility impairment would be best advised staying elsewhere (unless planning to get around by car/taxi).
