The location is great! Super central and right outside the tram. The apartment is nice. The wifi, however, did not work for me (I ended up leaving before the issue could be resolved), but yeah, the WIFI did not support more than one electronic device at a time and constantly broke. I also did note that there was no cleaning service between me and the next guests as I just handed off the key to them. Additionally, the fridge would sometimes make strange noises AND there was dried food stains (sauce?) in the curtains by the kitchen. But, if you're only in Vienna for a couple days and are exploring the city anyways, I think that this is a good option. The location is unbeatable and it's a big flat.
