We spent a lovely three days at Christine's apartment over Christmas, and it was really the perfect base to explore Vienna from. Christine was super easy to communicate with and very easy going, and went above and beyond by providing us with much needed milk, bread and a lovely selection of Christmas cakes and biscuits for us to enjoy! Public transport in Vienna is extremely convenient and easy to use, and we had absolutely no trouble getting to the city centre and around Vienna's other sights. Christine's apartment was such a comfortable place to come home to after each day of sightseeing, highly recommended.
