I spent the past 6 months at Rainer's place. This is a little gem located very near one of the main attractions in Vienna and also the Messe Wien conference Hall. The location is quiet and also has nice surrounding areas for those who like a walk or a bike ride.
Very well located and with good services around. Within short walk of 2 metro stations and a 15 min ride to the city center. A couple of supermarkets and a bakery can be found nearby and a shopping mall can be reached with a short metro ride.
The apartment is very confortable and nicely decorated, wich is always a plus to make your stay more confortable. Sound isolation is not the best, but overall, noise levels were kept low, in particular during rest hours.
The common area of the building is a bit old, but is cleaned every week by a maintenance team. The only downside is that some of the tenants seem not to respect as well as others, the common areas. In particular in maintaining the cleanliness. That said, one does not spend too much time in the common areas anyway.
A word about the host. Rainer was always very helpfull before and during the stay. Replies quickly and tries to solve any issue that may eventually arise. He also provides at arrival, a handy booklet with suggestions and important contacts, to make the start of your visit a just that little bit easier. Do try the suggested Burger Bar. It's worth it!
Whether for a short visit or a long term stay, a recommended place if you are thinking of visiting Vienna.
