The stay at Dominik's place was really nice. The room is very clean and we got no problem with communication. He let me put my stuff in the apartment before check-in and also after checkout. Great location near to Line 6 and 4 (which can take you directly to most attractions like Schloss Schoenbrunn and Stephansdom), also just 10 mins walk to Westbahnhof. Very recommend for people, who don't have enough budget.
