She contacted me in advance to make sure I know how to get to the apartment and how to get in. She was very friendly and helpful, answering all questions I had. We met the on the first day, where she made sure that everything was alright.
The apartment was big enough for us, consisting of one small room, a bigger one, kitchen and bathroom. The rooms were very clean.
It was very hot in Vienna, around 35 degrees or higher. The apartment does not have air conditioning, but Oi provided us with a big fan whoch was sufficient.
The only thing that was not perfect is that the windows do not dampen the noise from the two way main street in front of the apartment enough, but ear plugs did the trick.
The apartment itself is very close to a subway station and a supermarket, which makes it perfect for exploring the city.

All in all, I was very pleased, and I would stay there again.
