Oliver has a great location and apartment and would recommend to any travelers going to Vienna. The apartment is located less than 15 minutes from a main subway station but if you don't feel like walking that far, there are several buses that take you directly to the subway. Very close to various attractions and those that aren't within walking distance can easily be reached by public transportation. Oliver provided several great restaurant suggestions which we enjoyed and was very quick to respond to messages. Check in was easy and he provided very detailed instructions that made finding the apartment easy.
Apartment is surrounded by local shops, restaurants, and cafes. I would absolutely recommend this apartment to anyone traveling to Vienna.
