Astrid is a very laid back and friendly host. I have only seen her once for 5 minutes though as we both were out most of the time.
The apartment is in the very center of Vienna so i could walk everywhere on foot. The neighborhood is very nice and loads of grocery shops near by as well as cafeterias and restaurants. it takes 10min walk to the Opera House and central streets.
The room was very clean and comfortable with internet. I would recommend this apartment and will plan to stay there again when i am next in Vienna.
