Matthaus's apartment is a great place to stay, well situated, lots of options to eat right out the door and easy access to public transportation.
The apartment is super cozy and very clean and has everything you need, from hygiene products to coffee, tea and a lot more.
The check in process is incredibly simple and if you have any problems the host will definitely help you out.
Matthaus is a great host, responsive and super nice, I had a great experience and would definitely recommend his place to anyone who's interested in visit Vienna.
