All in all a good stay. The house is old and it has its own charm, like any other typical viennese building from the turn of the century. However it is poorly equipped, especially the kitchen. Also don't expect a lot of furniture, it is quite rudimentary
The biggest issue however is, that the rooms on the ground floor are so close to one another that you can almost hear your neighbours breath, not to mention that the entire house has old wooden floors, so when someone walks or shuts the door close, you hear everything, thats especially annoying at 1:00am
Wifi is good, garden is nice, although the grill doesn't work ( no gas bottle during our stay, no instructions how to use it)
Like I said, all in all a good stay, but the house definitely needs improvement. As far as location goes, well I lived in Vienna for 10 years...and it's not fantastic. Yes, tram and metro are not very far away, but you need at least 25-30 minutes to reach down-town
