Bernadette was a very good host. She waited for me to arrive even if it was late, she offered information to get to her house and prepared for me a list of places I could visit. During my sort visit we had a few chats about life in Vienna, Italy and London, as well as my experience in the city.
The flat is nice and reasonably clean. As Bernadette says this I not a hotel, she has her own life and things to do and the flat looks like a normal clean living flat. So if you expect hotel standards this is not the place, but if you want a nice welcoming place than I recommend it!
Bernadette's place is at walking distance from the city centre so it's really not necessary to take transport. It take about 10-15 minutes to the Opera House and Albertina platz.
I definitely recommend to visit Vienna and stay at Bernadette's house.
