We enjoyed a lot our stay. We traveled together with our 2 y and 4 y old kids and the fact that the underground station is very close helped us a lot. The apartment is big, warm, very convenient for families.
We could hear the noise from the street, however this was not disturbing for us.
The shower is separate from the WC. We had more than enough towels, toilet paper, hand soap and shower gel.
The kitchen was quite well furnished for a family.
A bigger hanger for the jackets in the hallway might be a good idea. We managed to hang our coats on a chair, so this was not an issue. It is just a small recommendation.
Overall, it is great value for money which made our stay in Vienna quite pleasant.
Many thanks, Victor!
