We are a family of five adults and one baby, we stayed in this apartment for 7 days. Wolfgang is a great host, he has been very responsive to our questions prior to and during our stay.
The location of the apartment is very convenient for visiting Vienna. you can walk to many tourist sites, there is an underground station a few minutes away, grocery shopping right downstairs. A parking garage is also next to the building. Many restaurants are around the area.
A couple things that would have made our stay more pleasurable.
A couple of weeks before our arrival, I was told the terrace is under repair and we cannot use it. This is one of the features that it was advertised for and I think we got short changed. It looks like the terrace will not be ready for a while and the host should remove this feature from his page.
There is water damage on the bathroom door frame, which is not new. This has caused bottom of the frame to swell and door cannot be closed properly. This was not mentioned to us when until we asked.
