Andreas’s apartment is really well appointed. It is right in the middle of Vienna, and you can walk to all the main sights. It is quiet and comfortable and spotlessly clean, and the kitchen was fully equipped. Andreas was an excellent host and very responsive, spending time to make sure we had everything we needed and to show us how everything worked. The fridge was well stocked with staples when we arrived - and he gave us a bottle of champagne!
The one downside is that the apartment doesn’t have a view to the street, but as you will likely be outside all day enjoying Vienna, it’s not really an issue.
