Gisella (and Pia) were absolutely wonderful. They helped us with virtually everything: when somehow my reservation got messed up by AirBnB, arranging a taxi to and from the airport, meeting us in front of the building, making sure we had a map with all the highlights and showing us two great restaurants within walking distance. Btw, we tried and loved both. The wooden floors are so nice, the balcony is perfect for breakfasts and late night lounging with a glass of wine or two. Always a quick response, always incredibly kind and so helpful. Their help and lovely, immaculate and very quiet apartment ensured a very happy stay in sunny Vienna. The public transport is very efficient and within walking distance from the apartment. Very good for lazy people like ourselves :) 10/10 would definitely book again!
