Peter and Katharina were wonderful hosts! communication started early and was very clear and easy. they allowed us to check in early which was awesome since we only had a day- and when Peter met us he gave great recommendations on the city. the apt itself is in a great location- to the train station and also provides a lovely walk to the main shopping street and even old town if you like to get some steps in like we do. it was beautifully appointed and very comfortable. we would recommend this stay to any friends going to Vienna and stay here again if we have the chance to travel back to this great city.
