Me and my girlfriend stayed at Astrid's place for 4 nights. The apartment looked just like the pictures. There is a metro station very close to the apartment, with which you can go anywhere in Vienna.
The reason why I give it 4 stars instead of 5 is that towels and bed linen were left to dry inside the wardrobe in the bedroom. They were soaking wet. I am not sure why that was like that since there is a dryer in the apartment. We had trouble sleeping the first night because the bedroom was very humid and it smelled like detergent. We had to remove the towels and bed linen and put them in the other rooms. Apart from all this, the apartment is very good.
