Max and Raphael's place is a beautiful apartment, very well organized, furnished, clean and tidy. Moreover, Max was very welcoming and cordial, he patiently answered our questions and provided info about the apartment and the city. Email/text communication prior to the visit was also smooth. You can tell he is an experienced host. The location of the apartment is good and quite central, and a few minutes from a Uban station. Considering the efficient and compact U-bahn system in Vienna, it means you are close to everything. We had a very positive experience.
