The flat was incredibly beautiful, it had some artistic vintage flair to it. There were three sections, kitchen&bath, living room, bedroom. I didn't expect it to be so big like it was. It was clean for my standards and very comfortable. The speakers were a plus as I could play music in the apartment. The location was near the tram and bus. Which you could take to the main HBF and I think the city. Walking on foot from the apartment to the city took me 25mins. The apartment was extremely near the side entrance of Belvedere and there was a few shops and restaurants/bars nearby. Wifi was incredible. I did not meet Gerd as he was away but his neighbour received me. I reached at 1:30am, but he was happy to receive me still which was very nice of him. Gerd was very helpful, texting me a lot to help with directions and to ask if I was okay. Very very nice stay in Vienna. Will definitely recommend to anyone.
