2 adults, 2 children aged 3 and 1. 1 week stay. Wonderful, spacious apartment in the hip district 7. 1st floor with 4 steps from the elevator to front door. Easily walkable to trams, buses, horse carriage rides, metro, playgrounds, the MQ, and many other great restaurants. Loved visiting the ice cream parlor across the street almost everyday! The house has the old European charm with wooden floors and beautiful high windows. However, as it is an old house, we sometimes had trouble with the elevator and even locked ourselves out (which our wonderful host quickly helped us resolve)
With 2 young children, the house has more than enough toys to satisfy them for days and nights (that sometimes our daughter would rather go home to play with toys than be out at museums).
The host was so helpful and kind and eager to help us with our needs and answer our questions. We even had coffee and had a playdate with our kids in the nearby park.
If we must write a con, it's that we are short Asians and the kitchen counters were initially designed for tall people.
But otherwise an excellent place to stay in Wien. (We've been on the road in Austria now for almost 2 weeks and our daughter still keeps asking us when we're going back to Wien ;)
