The apartment is superb for one person. Everything is within walk distance: SPAR-Gourmet, Anker, and Billa, cafes, bars.
Cooking is doable, but space is limited - but that's just me who likes a big workspace in his kitchen.
Overall, if you like a cozy place in Vienna, I totally recommend this studio.
