We enjoyed staying at Plamen’s apartment. The place was very comfortable for the four of us - 4 adults. His apartment is 1, 2, or 3 train stops away from everything you might want to visit in downtown Vienna. You can also walk downtown, or visit the restaurants around his place. Having a grocery store a block or so away was very convenient. We enjoyed having air conditioning because it was hot and humid in Vienna during our stay. I recommend staying at his place.
