Nice place. Well located in the center of Altstetten near many grocery stores and shops. One block away from the tram (a big plus). The apartment is really small but it is very modern and beautifully decorated. The balcony is really nice.
At times, the noise from the street can be a bit bothersome, but closing the girthy windows will dampen it. Also at night, some of the light from the street posts will seep in a little bit.
