We loved the apartment It's just as described, bright, lots of natural light, brand new, modern and close to the train and tram station. It was very quick and easy to get around town being so close to the station.
We went to the historic district by tram for sites and dinner but we also stayed in the neighborhood and walked to some very fine restaurants.
The station has a large grocery store along with other nice shops.
Illia was very easy to communicate with and answered any questions we had right away. We will definitely make arrangements to stay at his apartment the next time we are in Vienna.
