Due to overrunning renovations at the Karlsplatz apartment we had originally booked, we actually stayed at the Rochusgasse apartment (https://www.airbnb.co.uk/rooms/1122253).
We had booked the apartment for our Honeymoon for a week and our stay could not have been better :) As we arrived, we were warmly welcomed by Melanie who explained everything about the apartment very well (how to work out the dishwasher, which keys to use, the TV...). She also gave us good advise about transports and tickets, showed us where we were on a map and recommended areas where we would find good restaurants. She also said she would be very happy to help if we needed any help or advise about anything. A bottle of wine was waiting for us and the day to day things we needed such as washing machine powder, dishwasher tablets and even coffee pods were there (very handy as you don't want to buy it, use a tiny bit and then leave it all so very much appreciated!). The apartment was brand new and just so lovely with lots of features that gadget lovers will enjoy... ;) Highly recommended!
