Yvonne is amazing! She is the quickest host we have encountered in terms of responding to messages and recommendations. Her place is not quite in the centre but we liked the location and the walks every morning; takes about 15mins walk to get to where the attractions are in centre. Check in was very easy as well with details provided by Yvonne prior to arrival. She also helped organise a taxi pick from the airport which was really easy. We will definitely come back here if we return to Vienna. Another outstanding thing is the cleanliness of the flat. Loved it!
