Ekaterina's place is wonderful - it is extremely clean, cosy, located in a very safe area and is very close to the local metro station. She was a fab host and answered any questions we had promptly. Unfortunately we were unable to meet Ekaterina on this occasion as we had a very late check in but she was super accommodating to this and we had no issues checking in/out. She was even happy for us to leave our luggage until later as our flight was in the evening. Overall a fab place to stay and I would 100% recommend it if you are in Vienna!
