From start to end, I had a great stay at Anna's apartment. Not only is the place ideally situated, the metro station just outside the door, but it is quiet enough as well for a good night sleep.
It is also in the center of the city which means I also had the option to walk to all the main attractions if I wanted to.
But the best thing was Anna's welcome: she made us feel like we were at home since the moment we arrived, and made sure to answer all of our requests with care, professionalism and kindness.
All in all a well deserved five star stay.
Thank you Anna! I definitely know where I am going to stay on my next visit to Vienna.
