Justina's apartment is a great choice to stay in Vienna. It's situated very close to metro station, also you can easily walk to Central Train Station (it's one station away). City center is a bit further, but if you like walking - it's absolutely possible. Apartment has a fully equipped kitchen with all you may need and even more, including different teas, coffee and even juice in refrigerator. Bathroom is very warm - it's was super important for us as we were travelling in winter. Also special thanks for the warmest blankets - looks like they saved our lives :)
Though unfortunately we did not meet Justina in person due to very late check-in, she left very clear instructions how to get to the apartment, and inside we found all necessary information about the apartment and recommendations of nearby cafes and restaurants. We tried some and all of them were definitely the right choice!
Apartment is highly recommended to everyone!
