Our stay was nice for a short trip to Vienna. Aniko had a good and responsive communicatiowas and also flexible on check out time. Location was easy to access with public transport and it was possible to walk downtown also approx 25 min.
As a suggestion I would recommend to replace the mattress as it was made of two separate mattresses which during the night were separating apart and creating a hole in the middle which was not very comfortable to sleep on.
A part from this we had a great stay!
