We had a lovely stay at Andrei's apartment. It was just like the photos, very clean. He provides with everything needed (tea, coffee, towels, soap). The apartment is ideally located, in the city center. Andrei was a really nice host, attentive. He welcomed us himself explained us everything. We did not see him much during our stay but he responded to email very quickly. I would definitely recommend his flat for a trip in Vienna.
