Christian's place is really ideal for folks who are visiting Vienna but don't want to be in the middle of everything the entire time. The neighborhood is quiet at night & not at all crowded, the building that the apartment is located is quiet all day, and the unit itself is very nice. We came back to Vienna as a family, so it made sense for us to have a place that had 3+ BR in it for our troupe but it would also be incredibly easy for 3, possibly 4 couples to share the apartment with a reasonable expectation of privacy during their stay.
The kitchen is well supplied with dishes & cookware & there is a Euro Spar literally just around the corner from the house with a great selection & helpful staff.
There is a Wienerlinien (tram) stop right outside the building that allows quick & easy access to the city center via Karlsplatz - we visited the cathedral, Rathaus, & 7Stern Bräu this way. My wife & I love to walk but the rest of the family not so much, so it was nice to be able to hop back on the tram & go home after we ate.
Christian was a gracious & communicative host, answering our questions very quickly & effectively. He also stocked the home with all of the essentials, towels, sheets & blankets, etc.
I promise you won't regret booking this place.
