We stayed in Philipp's apartment for 5 nights in Jun 18. This is a big apartment !
Pre-arrival communication with Philipp was great and the check in was simple and straight forward. The apartment was clean with all amenities provided - in fact, the apartment is exactly as portrayed in the Airbnb description.
The apartment is maybe 50m from the nearest metro (U-bahn) station with easy access to the centre of town - maybe 7 minutes ! Very central to all of the sights.
There are supermarkets and restaurants within a couple of blocks of the apartment so all that you can need is close at hand.
I would highly recommend Philipp's apartment to anyone intending to visit Vienna. You will not be disappointed !
