We arrived in Vienna very late. We got our taxi right outside the airport to the Air B&B for only €45.
There was a shop very close (5mins walk) so we were able to get some bits.
The main city was about 25mins walk which was a lovely walk everyday because we had beautiful weather. The palace was an hour walk but only 20mins in the train. It was so easy to get there and it landed us straight outside it.
The apartment was as described, there was a washing machine and dishwasher. There were lots of gluten free and dairy options in the shops and restaurants. Overall absolutely amazing
