Isabella together with Constantin, her boyfriend, warmly welcomed us in her awesome flat. They were so nice that Constantin carried our luggage and offered us a Champagne when we entered the room. The flat was AMAZINGLY furnished - very fancy and homey. The train station is just 2 mins away (you'll find small food stalls there if you get hungry at night - restus and shops in Vienna close pretty early). From the train station, you can easily access the cathedral, museums, volksgarten (my fave place in Vienna), Central train station, etc. the supermarket is also 2 mins walk. We stayed in the flat for 4 days and I'd definitely recommend the flat of Isabella when you're staying in Vienna ! :)
