The place is great!
It has everything one could need on a trip to Vienna. The location is only 3 stations from the old town. Just across the canal there is a big public park with many children`s play areas. The street is very quiet and away from traffic and other noises. Shops, cafes, restaurants are all in a walking distance if one decides to have dinner near the apartment.
The host replies fast and is very helpful. Both baby crib and high chair were made available for us (Thank you!).
Maybe the place is not located in the most vibrant area and it takes a little time to get to places but for our family and for our trip it was perfect!
