It was a excellent mini-vacation in Vien. Michael was all time online with fast responce to all questions from our side. Apartment is excactly as shown on photos - comfortable bed, cozy rooms and linen. Kitchen is equipped with all utencils and appliances - modern tableware, dishwasher for the cases if you will be lazy to go outside to eat.
Apartment has a really nice and comfortable location - a large (if not largerst in Vien) park aside - Prater with attractions, a lot of spaces for walk/hiking/bicyle and a lot of childs playing grounds. Transport reach is excellent - subway station nearby with just one stop from subway transfer station with a railway connections, from where you'll have convenient connections to airport (~25 minutes away - S-Bahn not Airport Express). The first station (Messe-Prater) is within 2-3 minutes walk, the transfer station/railway station (Praterstern) is within 15 minutes of quite slow walk.
The only pity was that Prater messe attraction were closed for some maintenance/holidays - exactly on the week of our visit.
We highly recommend this option for stay in Vienna.
