we stayed at bettina's apartment for 2 weeks with our two kids and dog, and it was wonderful. bettina went above and beyond to make us feel at home. she baked us a cake and had some local beers in the refrigerator for us upon our arrival, was easy to communicate with, and even gave us a christmas tree! the space is clean, modern, and comfortable (incredible shower and stand apart bathtub). the apartment is a 5-10 minute tram ride into the downtown area, but the public transportation in vienna is incredible so it's super easy. only thing to note (which is also mentioned in the description) is that there is a small music club in the basement of the building. they have a midnight curfew but you will hear some noise from it.
