Me and a friend stayed 3 nights in Jérôme's flat in Vienna.

For us, the location of the flat was perfect! We arrived to (& departured from) Vienna by train, and the Medling train station is just a minute away! This was very convenient for us since we had a lot of luggage. Whilst the location of the apartment isn't exactly in the absolute city center, there are very good transportation alternatives. You can easily take the U- or S-bahn to the city center in just a few minutes. We bought the weekly-transportation-card (which was cheap).

Jérôme was a great host, supplying us with a lot of useful information and tips. The apartment was clean and had all the things it promised -- we were very happy about the quality of the apartment!
