Werner is a very friendly and helpful host who is also an architect. This explains the neat design of this apartment which I stayed in for four weeks. It is warm and cosy with a very comfortable bed. The bathroom and kitchen area are both very small but adequate for one person or a couple. There are S-Bahn stations nearby and you can be in the centre (Opera/Karlsplatz) in 10-15 minutes. A supermarket and other shops are within 300 metres so everything is very convenient. I recommend it without hesitation and would happily stay there again myself.
