My twin and I very much enjoyed our stay here. The apartment is beautiful, in a great location (surprisingly quiet at night given how central it is) and very comfortable. 10 minute walk takes you to the U4 line (Pilgramgrasse) which can get you into the centre of Vienna super easily. The kitchen is not the best stocked (basic utensils, lacking things like cooking oil, sharp kitchen knives etc.) so, if you’re staying more than a few days and want to cook there, you’ll need to do some shopping. Fortunately, there are some good shops nearby. Finally, the shower will easily flood the bathroom so make sure to put a towel down next to it - very small issue. Overall, I’d highly recommend the apartment - to make it a perfect stay, I would have liked to have seen a great range of utensils.
