We found Nina's place last minute, because our previous AirBnB wasn't as good as it seemed... And we're glad we found Nina's apartment! It's well situated (metro is easily reachable), and it's very clean and confortable. Everything you need is there, check-in and check-out is extremely easy and Nina is very flexible. Great communication, great place, and great stay! I definitely recommend Nina's place for your trip to Vienna : )
