Katharina's apartment was great for what I was looking for. I was working in Vienna at the airport for several months. The apartment is situated just 10 minutes walk to Wien Mitte train station, which is connected to the main line directly to the airport. The apartment is also very close to the Donaukanal and Prater, which offer a nice natural element to the city. Just 10-15 minutes walking from the apartment is the most central point of Vienna, all major attractions are within easy walking distance, train distance or tram distance and all required stations are very close by. The apartment itself is on the ground floor and was complete with everything I required for a lengthy stay in Vienna including cooking utensils, pots and pans, oven, dishwasher, washing machine, cupboards and hangers, ironing board and a small dining table and chairs. The bed sheets were changed regularly by a very friendly lady who also brought toilet paper, cleaning materials and anything else that was required. The apartment is clean and tidy and Katharina was very quick with responses whenever I messaged and more than happy to help with anything that I asked. This even included when I needed to order something to the apartment from abroad, Katharina was very helpful in helping me organise the delivery and collection of the parcel.
In terms of daily amenities, there is a Spar store, less than 5 minutes walk around the corner from the apartment and also a Superspar within the Wien Mitte mall (Same place as the train station).
I would happily recommend Kathrina as a host and her listing to anyone wanted to stay in Vienna on a short or long term basis.
