I love the location! The famous Nashmarkt is just downstairs. Next to the Kettenbrückgasse Metro Station (just 1 min walking). And it's heut one station to Karlsplatz station, from there you can take U1 to the train station.
The apartment is very clean and sweet. We all slept very well. Cristina does have a really big bed!! And if you travel by three, it will also a good choice for you.
Cristina is such a friendly and considerable hostess. Everything went smoothly such as check-in and check-out.
We've enjoyed the stay there!
I will definitely recommend her lovely place, if you want to find place in Vienna to stay.
