Erich is not the owner of the house, but he was there to check if everything was ok. The owner and his family showed us around and gave us good tips of how to get around Vienna. It is very close to the BigBus tour's stop, which made it easy to travel around Vienna with a family. It is also close to the Museum Quarter and many restaurants and cafes in Vienna (food is not that cheap in Vienna). There is no air-conditioning, so it gets a bit warm at night in the summer. Other than that, it was a good stay
