This is a very good apartment for a family group (in this case 4 adults including 2 elderly adults, and 2 young kids), especially for a longer stay. Advantages include two toilets, two showers (where one has a bathtub), two washing/drying machines, big bedrooms, and a cosy, spacious common area. The painting of the cow in there is fantastic.
The location is excellent, with a short walk to the U-Bahn (U2 line), a tram line, a few grocery stores, various non-touristy restaurants, etc. There is a lot of opportunity to get take-away if you don't want to eat out, or of course you can find some nice local ingredients and prepare your own meals. The knives could do with some sharpening though.
Only real downsides were street noise and noise from construction that starts early, but it's not really possible for the hosts to do anything about that. I wasn't too keen on the Nespresso machine either, but different people have different opinions about that one.
