Rene was a polite and courteous host and was able to accommodate us even though we arrived earlier than expected.
The apartment was well set up and had everything we needed, including a washing machine! It was very hot when we stayed in Vienna (early June) and the apartment did not have air conditioning or a fan which was quite uncomfortable.
The neighbourhood was not the best, I suggest researching the district before you arrive. We stayed here to be close to Westbahnhof however the public transportation system is excellent so you don't need to be so close to get there easily.
