We've spent four days in Vienna at Eva's apartment, and we highly recommend it to other guests.
The apartment was tidy and clean, the bed comfortable and well made: an induction hob is present, as well as any dishes you should need; the room is wide and well-lit.
The bathroom was a bit narrow, but perfectly cleaned and had everything - even a washing machine for longer staying; also, soap and shampoo are provided.
The position is perfect. You are just 5 minutes away to Karlsplatz station, but if you like walking like us you can basically reach every place. The opera house is less than 10 minutes away, Hofburg is 15 minutes away, and you are basically in the center of Vienna so each walking can lead you to visit and see something new.
The apartment also comes with some little sweet touches: a bottle of wine, two little bags of chocolates and a printed photograph of your Airbnb profile pictures: that was very nice to find.
Eva has been a perfect host. In the days before our stay, she has always been available to give us clarification about the COVID situation (there has been a lot of changing laws), and also accepted without any problems some reservation changes we needed for this reason.
Communication was easy, precise and fast; the check-in was quick and gave us all the information we could need.
The apartment is located on the 4th floor, and unfortunately the elevator was broken for our entire stay: realizing you forgot something in the apartment while going for a walk and you need to walk up and down again was not nice! However, I don't think the host can be blamed for that.
In conclusion, I highly recommend this host and apartment to everyone visiting Vienna (that is a wonderful city, by the way). Besides the broken elevator, the 5 stars are absolutely deserved!
