Our stay with Marie was amazing!!
We stayed for 3 nights to visit the city and be tourists. She provided us with some very very useful insider tips which we of course had to check out and had an amazing authentic but also very relaxed Vienna experience. The apartment is in a great location (although kind of difficult to reach from the Erdberg VIB station) is clean, large and very modern.
We definitely recommend you stay with Marie which we will try too the next time we come to Vienna :)
