Michael's place was nice and I enjoyed my stay. The flat is a equipped with 'smart' technology. It is quite trendy with a water mattress (make sure you are comfortable sleeping on a water bed). The location is in a rather residential area, which means it is quiet. There are two nearby subway stations and supermarkets that are a close walk. It is definitely not a place to go out and truly explore 'the heart of Vienna.' I was there for business and it had all the right amenities. I dd not spend much time in the flat because I was working most of the time during my stay. Depending on your purpose of travel, I would take that into consideration for this flat! Michael is a very lovely guy!
