Everything that the host describes in the Airbnb listing is accurate, so I won't belabor a lot of repetition.
This was my second Airbnb experience in Austria and it was amazing. This is an apartment that in NYC would sell for well over $1M. It is immaculate, with superb windows that completely block any street noise, but also open to allow fresh air in. The kitchen is completely useful and even has a lovely espresso machine (with enough packets on hand to get us going).
The location is the most amazing part. Everything we wanted to see was within walking distance, with the exception of a hop-on bus to Shoenbrunn palace.
Our host met us, gave us a rundown on the place, and speaks perfect English (and tolerated my less than perfect German).
I feel so fortunate to have stayed here.
