Isabellas Appartement is very well located within walking distance of two subway lines. So perfectly suitet for a city trip. I really enjoyed the quiet appartement. There are plenty of restaurants and shops within walking distance in case you do want to stay close in the evening. Isabella is easy reachable and very responsive. I had a great experience when checking in and out. As I was already a couple of times in Vienna, I did not had to get any directions, but I am sure she will help you with tips. For sure I will try to stay again there for my next Vienna trip. Highly recommendable.
