Lena and Ines are two kind and nice girls. I have not spent much time with them because I have been in Vienna for working and I was very busy. Anyway, they have been very polite and never noisy or messy.
The apartment is located in a wonderful and green district, and the underground is very close (5 minutes on foot).
The room was comfortable but a bit tiny, neverthless I ensure that you won't need a big room in Vienna, because it is such an amazing city that you would go around the whole day.
In general, the apartment was clean and the wi-fi available.
I warmly suggest these two nice girls and their lovely apartment.
