Andrea's apartment is very nice, it has a functional and compact kitchen and bathroom, with everything you might need for your stay. The flat is on the 11th floor and has a cool and spacious balcony, with a great view over Vienna. Public transportation is very close to the apartment, especially tram and metro stations. Andrea is communicative and chill, we had no problem arranging our meet. She even offered to pick us up from the bus station by car, which was super nice.
Overall, if you're looking for a cool smaller place to stay while in Vienna, with all the amenities and a great view, this is it.
