Rainer’s apartment is very comfortable, clean, cozy and quiet, you hardly hear a noise from the street or the neighbors. The location is very good, it is close to the train and metro station and it has tram stations nearby. Rainer is always willing to help, he gave us the best local recommendations and tips and lots of information that made our staying more easy and interesting. If we visit Vienna again we'll surely stay at Wien Mitte.
I would highly recommend this place.
