Nice modern design and pretty standard (if sparsely furnished) carpeted rooms. Cleanliness perfect, staff friendly and efficient. Breakfast only average considering the steep price. For my two night stay, I paid slightly under 50€/night for a single incl. breakfast and thought it was only ok value given its location. Public transport with daily service (S-Bahn stop Leipzig Messe) is about 12min walk away through a largely deserted commercial area (warehouses, empty lots), though there is a convenient bus from Leipzig main station out (number 196, about 1/h)
Overall a nice place but probably more suited to a single night stopover. Location really only practical for the fair unless you have a car. Plenty of street parking, don't bother with their lot. ´
Would I stay again? In a pinch, yes. Clean room, relatively reasonable rate. I'd probably not bother with the breakfast.
