Josef is friendly and his apartment is as unique as his personality! We had to cancel one night because our flight was cancelled, and it was delayed for two hours the next day, but Josef was very patient and understanding. Wifi is great. Great for short stay as the house is a site of its own, not suitable for elderly because you have to crawl haha.

It's not the closest to the tourist attractions, but the public transportation system is excellent in Vienna. Neighbourhood is not ideal so best to be alert.

Overall great experience if you love architecture, everything was mostly DIY but it feels safe and secure.
