We had a lovely stay at Christana’s place. Everything was as we were expecting and she was very helpful and supplied us with beach towels so we could go swimming in and sunbathing at one of the many swimming spots on The Danube.
In her notes there was very good advice about ordering a taxi from the airport, which was much easier and costing the approximately same for 2 people cutting out the convoluted public transport option with changes to be made. The taxi firm like 24 hrs notice and will be ready to pick you up at the airport. We thoroughly enjoyed Vienna and the grandiosity of the city and all it has to offer tourists.
