The house is amazing. We stayed in the 3rd floor (so be aware if you had trouble moving).
The location is about 5-10 minutes from tram to the center which is exactly in front of the house. The transports are really nice around Austria and you can get a pass for 1, 2 or 3 days for all transportations (not expensive).
The only issue we had, was that the heating of the house was turned off since day 1 so we had 2 cold nights before being turned ON the last night.
I really recommend this house, just make sure that the heating is turned ON once you arrive :)
