It was a very pleasant stay at Florian's apartment. His responses to my messages were prompt before and during my stay. When I arrived, he couldn't be there but arranged the key pick-up in advance, and everything worked out well. I enjoyed chatting with him and his girlfriend during my stay, and appreciated that I had access to their kitchen and washing machine. The location of the apartment was convenient, as it took only 10 mins on foot to reach the University of Vienna where I was attending a conference, and was easily accessible by public transportation as well. I'd recommend Florian's apartment to others!
