Enjoyed staying in Vienna. Nadia's father Markus was very helpful and the one room apartment was quite roomy, comfortable and spotlessly clean. Loved the huge bathroom. Extremely close to both trams and trains (3 minute walk) - just 10-15 minutes journey to the city centre. A very good cafe for dinner just 30 metres away which was wonderfully easy to visit after long days of sightseeing and walking through the old city. Supermarkets also very close and with an oven and stove top in the apartment we could also prepare breakfast and dinner ourselves. We arrived quite late but this was not an issue. It was however an expensive trip from the airport by taxi. I don't know how long it would take by train but would definitely try. Would recommend.
