Daniel is a great and very welcoming guy! He really went out of his way to make sure I had a pleasant stay. Communication was super easy and I felt at home from the outset. The flat is very comfortable and absolutely spotless, with first-rate equipment, plenty of sunlight throughout the day and amazing views. The metro is really close (2 min walk). I stayed with Daniel for my first weeks in Vienna. His advice on how to enjoy and move around the city definitely made things a lot easier for me!!
