Cleaner does a good job. Our impression was host just wants your money and nothing else to do with you.
The apartment has two levels. The bottom level has heating, while the top level has none. In winter, to try and heat the top level - where you sleep - to a temperature above cold, you need to make downstairs uncomfortably warm. Neither is comfortable.
Host is totally unresponsive. We came to Vienna with a car. We asked host about parking a couple of times before arriving - no response. Parking in Vienna is really complicated - if host doesn't want the hassle of addressing these questions, could at least print out key information and location of parking houses nearby to put in apartment. Having no advice around parking and not hearing back from host was a real pain for us and affected our feeling about the stay in the apartment very negatively.
Door leading outside could not be shut properly, letting cold seep in. One curtain was broken and hanging, so people could see in from street. Even if curtain hadn't been broken, the way they work offers little privacy.
The curtains upstairs are just office blinds, so light from the street floods the room, making it hard to sleep. The pillows are like a bit of mist inside a pillowcase - it is like not having a pillow at all.
Streets are busy and tram going past is surprisingly noisy.
There is a Spar supermarket really close, which is good. The cafe across the road was closed so we didn't have the chance to try it. Apartment has basics like salt and detergent.
Shame about our stay - if the owner just made a small effort with apartment and communication, the whole experience would have been so much better as the apartment's basics are fine and wouldn't take much work to make it all 200% better.
