Had a great time at Marcel’s. The flat is stylish and modern. Got everything you might need. Takes 8-10 minutes to U3 and 3-5 minutes to train number 2, which will take you straight to the center in 20 minutes. Several supermarkets - spar, bills, hofer. So I sincerely recommend Marcel as a host and this apartment as a place to stay for a few days in Vienna ! Thank you, Marcel!
