I really enjoyed my stay at Mladen‘s flat. It has just been refurbished, is fully equipped (full size oven, hob, microwave, espresso maschine...), and is located in a quite neighborhood (which allowed me to sleep peacefully).
Although it‘s not located in the city center, the public transport accessibility is fine, and the nearby district center of Währing offers everything needed for daily life (supermarkets, restaurants etc.).
Communication with Malden was easy and fast. My full recommendation.
