Barbara's place was amazing. It was easy to reach and underground was within a 5-7 minutes walk. Place was beautiful and comfortable. It was CLEAN, not just regular clean but "Monica clean" :D. Barbara was the best host, she was helpful, welcoming and friendly. If I am ever going to visit Vienna again I am not going anywhere else. I just can't oversell this place. Everyone.. If you want to have a best Vienna experience, Barbara's place is the first thing you should start with.
