Thank you, Simone!
The owner is very nice person, it's pleasure to communicate with her, we arrive earlier and she let us to leave our bags and gave some recommendations to us.
The flat is very stylish and has everything we need for comfortable stay. It's situated in a very good place not far from the city center, just several minutes by tram which stops at the corner. There are several supermarkets near and a good cafe at the ground floor.
We will recommend this flat to our friends and we will stay here on our next trip to Vienna.
