We had a lovely 4 night stay in Hans' apartment. Hans was easy to contact and very helpful in introducing us to the apartment. For just two people, the apartment is huge and could comfortably accommodate more people, but for just two people it provides for a luxurious experience. Just some things to note: the double bed is just two single mattresses pushed together with two single duvets. The kitchen we found to be fully equipped with everything we needed, and, with an affordable supermarket (Hofer) just round the corner, is perfect for anyone who intends to cook while staying there. The location was extremely convenient for exploring central Vienna, with the Zieglergasse underground stop next to the apartment. The hand shower in the bathroom might annoy some people but was not a problem for us due to the roomy bath.
