Pros:
1) location is accessible and convenient
2) room was huge with high ceilings, and very clean
3) wifi was fast and water was hot
Cons:
1) I had a few questions after I checked in. They were quite varied in nature and required different types of responses. Kaylee replied not promptly in a single paragraph, and said she wasn't currently at the location and to look for the stuff myself. I also asked for toilet paper three times over three days and Kaylee did not respond to any of the messages. There was no toilet paper in the apartment for the first 3-4 days I was in Vienna, until Christoph (the co-host) dropped off two rolls (thank you!) and also checked in with me for the previous queries I had (irrelevant by now). I had to cut my trip short because of a family emergency, and I'm not sure if it was an automatically generated message, but Kaylee reminded me to check out, although I was already home (18+ hours away by flight) by then, and had communicated my early check out to Christoph in the same message thread.
2) the shower space is quite small. The shower curtain (originally white) is been stained brown at the bottom, possibly from guests peeing in the shower.. To avoid touching the shower curtain, the outside area invariably got wet, which made accessing the toilet area challenging. It was a fun couple of days with no toilet paper and an unfriendly shower area.
3) there's no air conditioner in the flat. It wasn't listed and I wasn't expecting it, but the only windows face a small courtyard with high buildings on all sides, so while the apartment is ventilated, there is no air circulating which makes it quite stuffy esp in the summer months. A portable fan would have been great!
