My girlfriend and I spent two nights at the apartment and had an absolutely brilliant time. Christoph was an amazing host, very friendly, super helpful and he even gave us some great tips on where to go and what to do in the city. He also showed us the local Christmas Market. The place was easy to find, 5 minutes to the U6 metro and within walking distance to the city centre (20 minutes). The room was very spacious, clean and fully equipped. We would happily stay there again and would recommend his place to anybody who's thinking about spending some time in Vienna.
