The stay overall went well, the room itself was clean, and STK provided soap and clean towels.
Unfortunately, although my stay was short there were a few issues, starting with locating the room/building itself. When I searched the address provided on the app in Google Maps, I arrived several blocks away at some (very nice family's) house who informed me that I was not the first lost traveling student who had arrived at their doorstep looking for this particular AirBnB. (I really hope STK sorts this issue out!)
Once they directed me to the actual location, a welcome ambassador helped me to the room. Once again, the room was very clean (although I did not expect to need to buy my own toilet paper...) but the common area was quite messy and smelled bad - the photos of a colorfully furnished common area do not correspond at all to the reality of the situation.
It was a bit difficult to fall asleep the first night as the room is right above the building's main entrance where students congregate to smoke and talk, but I always felt safe at this location.
Overall I enjoyed Dublin and the location of this AirBnB (if you can find it!) is quite close to public transit, and the city centre is accessible if you don't mind a 25-ish minute walk.
STK responds very quickly to any messages, though I don't think I corresponded with the same person for more than two or three messages.
Next time I might go for an AirBnB with an actual host rather than a service.
