We want to visit Vienna again, just so we can stay here.
But seriously, this is a wonderful apartment. It's just a few blocks from the Mitte-Landstrasse station, which is both a U-bahn station as well as the terminus for the City Airport Train.
The apartment is bright, spacious, uncluttered and very quiet. Jonny was very responsive and easy to communicate with. The neighborhood is safe and has all sorts of conveniences - grocery stores, drug stores, bakeries, etc.
Highly recommended.
