Yuda was very helpul, first by giving us information by email prior to our departure, then on the day of our arrival - he was there to welcome us even though we arrived after 8pm.
The apartment is just one minute's walk from the metro and the tram station (they take you to the city center within 10-20 minutes), which was very convenient to discover Vienna.
There are several small supermarkets in the neighbourhood, as well as cafés and restaurants.
The flat was clean and tidy and there was everything we needed to cook. The bed was confortable.
We would recommend the place to anyone wanting to stay in Vienna for a few days.
