We had a nice stay at Sjelle's place, but there were a few quirks. First, Sjelle asked us if we could feed her cat while we were there, because she would be out of town for the weekend, which was totally fine because we love cats (and her cat Svedske is very sweet and friendly); however, it wasn't until the week of our stay that she informed us that Svedske is 20 years old, deaf, and meows loudly. We weren't really prepared for HOW LOUD the cat would be, and she woke us up in the middle of the night both nights of our stay, and we had trouble getting her to be quiet. We also felt like the apartment was a bit further away from the main restaurant / bar / shopping areas of Norrebro than we expected, based on the listing. We had to take a bus each time we wanted to go out in the neighborhood (the main bus is about an 8 minute walk from the apartment).
Things definitely weren't all bad, though, the apartment was clean, comfortable, and had a nice kitchen (though we didn't use it). The bathroom was small (as are most in CPH), but totally fine for our needs. Sjelle was also responsive to messages through the Airbnb app.
Overall, it was a good stay, we just wish we'd known what to expect going in!
