I stayed there for 2 nights as I had to work in the area. The after hour access with mobile key worked well. The studio was spacious and well maintained. The inside of the building had a good modern look (unlike the outside). Most needed amenities were available (fridge, stove, iron, iron board etc.), except A/C and.... breakfast restaurants! (if you're looking for breakfast, you need to bring your own - there's Coop supermarket 10 min walk). Also, despite double glazed windows, the building is at a busy crossroad, so a bit of noise (buses etc.). Overall, this might be a good place for a personal trip, or if you have to stay in Glattbrugg for work (not a lot of options there), but for rapid business trips I would consider hotels in Oerlikon.
