The flat is nice and was clean. Amenities are all fine and accurate. Beware, though, the flat is across the street from a 24h tank stop on a relatively busy street. During hot summer nights it can therefore be a bit painful to sleep with open windows. The wifi connection is through a router with mobile connection. That's fine in general, there are no restrictions, but at peak evening hours it could get unbearably slow and impossible to join online meetings.
Overall the building looks a bit run down, but it seems like it will be renovated soon, so your mileage might vary. The location certainly has its flair in the middle of the student quarter. There's even a narrow but impressive view across the city to Uetliberg from one of the balconies.
