We had a great time staying at Daniela's apartment in Vienna.
The location is great - 2min walk from a central public transport hub, including the city airport rail station and at the edge of the old town.

The apartment is just as described and has everything you need.

However, the most important thing is how amazing and gracious a host Daniela is. It started with her offering to buy us groceries ahead of our arrival, so that we can have something to cook / feed the children at our arrival (which was late evening after all stores were closed). It ended with an even more gracious and wonderful kind act:
I accidentally locked some of our luggage at the apartment right before getting on the taxi to the airport. It was 2hrs before the flight and we had to get on the taxi or miss the flight.
Daniela was away at a distant part of town, and it was on her weekend. Despite that, when I called her, she and her friend Martin, immediately got into their car - dropping everything they did - and drove all the way across to the apartment. They got the luggage into the car, and then sped to the airport. They made it in record time, just in time for me to check in the luggage before the counter was closed. They literally saved us. I don't know what we would have done otherwise.
I offered them cash to cover for their trouble, for the fuel costs, for everything and anything. Daniela and Martin absolutely refused to take anything. It was just a pure act of kindness.
If I had to ask for any future AirBnB host - I hope they are half as kind, giving and gracious as Daniela and Martin.
