This apartment is amazing! Especially if you travel by car - unlimited free parking. The place is huge by the standards of Vienna accommodation. The large queen size bed is very comfortable. It's just a short walk to the metro which takes you directly into the center. You exit the metro at Karsplatz and you are right in front of the Opera already.
The checkin and checkout was very convenient and the host always helpful. I really had a great time in the apartment and Vienna
