It's a highly recommended accommodation in Vienna central! It was in a very convenient location for sightseeing, very well furnished, and clean and comfortable to stay and to be relaxed. And above all, Eva and Michi are excellent hosts. They were kind and communicative. They gave me lots of information about Vienna and nice shops around the apartment. They also gave quick replies to my questions every time. Checking in and out were done smoothly, and there were no problems.
It was my first time of using Airbnb. I was a little bit anxious about the safety and cleanliness, but now, I can recommend their accommodations with confidence! I'm sure I will contact them again next time I visit Vienna.
