Christian was a great host. Even though I was late, he managed to pick me up from the station and walk me to the flat. He also had a lot of great recommendations for things to do in the city, places to check out, and restaurants to eat at and was always happy to chat when around.
The flat is perfectly situated to explore Vienna, a very short walk from the tube station and the tram takes you to the first district in not even ten minutes. The flat itself was spacious and clean, hosting all the necessary appliances. I really enjoyed the comfy bed and the big shower, so that I can really recommend staying at the flat and Christian as a host in general.
