We enjyed our stay in Oliver's apartment very much: the apartment is clean, spatious, fully furnished and full of light! The location is also very convenient: it is in a quiet residential street close to the Donau Kanal and the U-Bahn is just around the corner.
There is a supermarket within 5 minutes walk and a cheap car parking not too far.
In my opinion, Oliver's apartment is a perfect solution for spending a few days in Wien.
