We really enjoyed our stay, the apartment is beautiful and we especially enjoyed the outside terrace. We found the apartment easily from the train station and although we were early the cleaning lady, who greeted us with the keys, was very welcoming. We had a slight language barrier, but this wasn't a huge issue as she was so funny and showed us around the apartment.
Throughout the process Ellena was communicative and seemed to have a genuine care for our visit.
I would definitely recommend friends to stay here when visiting Vienna and I myself would return.
Thank you!
