Wolfgang's place is great, the best equipped apartment I've stayed in. Everything you could possibly want is available, there is plenty of room, and very clean and orderly. The location is well-served by public transport, adjacent to a commercial shopping strip, but pleasantly quiet. Wolfgang is a friendly and flexible host - was there earlier than initially planned upon my request, and was super-flexible with departure time. I would not hesitate to recommend this place to anyone staying in Vienna.
