I stayed at Roman's place for four nights. It was my first Airbnb experience as a guest. I did not meet Roman but we talked on the phone. Communication with Roman was very easy and he does his best that guests can enjoy their trip. Roman helped with information about sights, food and parking. The apartment was as described clean, modern and comfy. Location is also very good, I used U-bahn and station is 5min away. I had a great time in Vienna! Thanks!
