They are very kind ! The flat's location is very close to central station, it takes just 5-10min. So there are supermarket and cafe, bakery as well in the central station building. It was very comfortable. We just had one night there, so it was very short time. But Peter gave a good information to have a good day in Wien. Thank you very much! Central located, kind persons, well tidy and Clean! I recommend this flat with them :)
