This is a really lovely apartment with elegant high ceilings, beautiful chandeliers, and lovely parquet floors! So very Viennese!
The apartment is very convenient to tram lines connecting to places all around the city. The best thing is to buy a weekly ticket (€17.10, valid Monday morning to Sunday night) which gives access to buses, trams, and the underground. We went on the city tour bus, but honestly saw more from the trams!
There are two supermarkets very near to the apartment (Billa and Hofer) but keep in mind that supermarkets close on Sundays and Holidays (you will find supermarkets in the airport, train stations etc that do open on those days)
The CAT train to and from the airport is excellent value at €19 return if you book online, and children up to 14 are free! Taxis from the airport are expensive!
There are restaurants near the apartment - Café Weimar does a fabulous breakfast and is really Viennese. For dinner, Glasweise nearby does lovely food and really nice wines!
We would definitely come back to this lovely apartment! Christian is very helpful with local information and the apartment is lovely to come back to after a busy day!
