We highly recommend Anja & Christian’s place. It’s location on the tram line makes it super easy to get anywhere in central Vienna. It is in an old building, facing the courtyard which makes it very quiet and peaceful. We stayed in the summer and there was an AC unit in the apartment and the windows have blinds that help.
The apartment has a small fridge, stove, kettle, and all the kitchen house wares you might need. There are grocery stores, a laundromat, and plenty of bakeries and cafes in the neighborhood.
Our host was super easy to reach and answered all our questions instantly!
