Ulrich's flat is perfectly situated in central Vienna. You can easily walk basically everywhere in the city center. The apartment is very clean and seems newly renovated. The kitchen is well equipped, you'll find everything you need to cook there. There is also a nice big table to have dinners and two comfortable sofas to hang out. We were two couples spending a week over Christmas there and loved it. We would definitely recommend Ulrich's flat to everyone.
Thanks to the great host!
