It was amazing experience especially with Victor.
Tips for winter visit in Vienna: Take some warm clothes with you in winter times.
Transportation: Very easy to pick off on Johnstraße U3 Station, a few minutes by walk. Also the tram which is passing through from the street is directly going to Volkstheater tram station.
Markets: Penny Markt, Billa and BIPA is only by a few minutes of walk.
Furnitures: Easy to use microwave, filter coffee etc.
Only negative thing is being cold during the winter times of Vienna.
Thanks for everything, appreciated to have this experience!
