Eileen was an amazing host. She always responded quickly and the pictures do not do the apartment justice.
I was in Eileen's apartment for a month and the place looks better than the pictures. The public transport was easily available, as there are tram stops and bus stops near by. And there are numerous restaurants and supermarkets nearby.
The neighbour, David, was very helpful and provided a wealth of local knowledge and tips. I would recommend Eileen's apartment for a long or short stay in Vienna.
