I spent 4 days with my family in Mario’s house and we felt like at home. It has everything that you need. The kitchen is very well equipped. When we arrived the house was very clean and warm, something that we appreciated as it was 0 degrees outside.
The location is perfect, you can go by tram everywhere and it doesn’t take longer than 20 minutes.
Very easy and convenient self-check in and check out.
I would definitely come back if I go to Vienna again!
