Good tip with the parking at P+R Hutterdorf. Easy to find a parking spot on the street just out the window, however it was not so straightforward where to pay for parking (only at TABAK stores and metro stations). The apartment is next to U4 train however there is no noise, even with open windows. Fans really helped at temp above 30deg C outside. Some other reviewers mentioned construction outside the building, but it seems that it is done now, so no noise or rubbish outside. All in all, a great place for a family to stay at.
