My friend and I had a pleasant stay at Rainer's apartment. He was very helpful...he waited for us from the window, and when he saw us, he immediately came down to help us with our luggage. The apartment is huge, so is the room, its right near the kitchen so is very private. We only met him on the first day as he had to leave on urgent matters but he had arranged for our stay in Vienna to be pleasant. The location is superb, right in the city centre!!! Thank you Rainer!!!!
