This flat is one of the most interesting spaces I have ever stayed in, you can definitely tell it is owned by an architect :) The 'shower box' is very clever! The flat was also clean and had a lot of lovely details (house plants and cut flowers, reed diffusers) that made it feel super stylish and cosy.
I was a bit hesitant about the toilet cubicle being in the outside hallway and the washing machine being a shared one in a cupboard one floor up, but actually these did not prove too inconvenient. Only problem was someone who left their laundry in the machine long after their cycle was finished... what kind of babarian does that with a shared washing machine? But that's just a minor grumble. I stayed at this flat for a month and would happily have stayed for twice as long!
Location-wise, the flat is also great. There are two supermarkets just a five-minute walk away, Billa and Spar. Also just round the corner is the 2 tram that will take you into central Vienna (around 20 minutes), or actually I often walked as I like walking (around 40 minutes).
