I stayed one week over at the Flora Möhringen hotel while I was exhibiting at a trade fair in Stuttgart/Leinfelden.
The room was spacious and comfortable. Because the hotel is off the main road, it was quiet. Price was fair enough (130€ with breakfast) in this time of year where it is really busy with business events.
Beware that you should book a parking place in advance to be sure to have one as places are limited in their underground parking (+6€ / day).
Free flawless wifi.
The staff is friendly and professional.
I missed the possibility to eat on the spot (there is no restaurant) but there are plenty of restaurants in the surroundings so not really a problem actually. You can get any type of food within a 5 minute walk (pizza, German-style restaurant, kebab, ice cream...).
There is also a convenience store only 2 minutes away.
