First of all, the location of this Airbnb is absolutely UNBEATABLE, as everything is within a walking distance. Not only that but you're staying withing Old Town already, amazing!
The place itself was spotless once we got there, the bed was comfortable, the restroom was clean, the kitchen was fully equipped, and the living room was open enough not to feel squished in. Olof was very responsive as well and we never encountered issues getting in or out of the Airbnb.
Now that being said, I must also add there are some details that you may want to consider: this place has almost no natural sunlight coming in at all even with windows and door open (note: we went during winter, and sunlight was extremely limited already), the place can get a bit chilly as the heating turns off at night and the radiators are not necessarily enough, and the hot water is a bit inconsistent.
Personally we didn't mind these a lot as we spend most of our time outside, but keep this in mind.
Great stay!
