Fredrik has been a nice host, he has responded swiftly to our enquiries and has always been very welcoming. Perhaps, I would have appreciated more proactivity from Fredrik regarding the (very minor) things that did not work in his apartment. However, once flagged, he showed a decisive attitude towards solving them.
As for the apartment, the first thing that stands out is the tiny size of the rooms, the kitchen and the bathroom. They are by no means spacious, so I would recommend acknowledging that in the description of the flat. Things like trying to cook between two people get quite uncomfortable. Additionaly, the lack of a microwave makes this Airbnb even less attractive over other modalities of accomodation due to the unavoidance of eating out-related costs. Moreover, the apartment is in the ground floor. This was not a problem for us, since we did not spend too much time at the apartment, but it could pose some concerns in terms of privacy to other guests. Lastly, even though the apartment can be considered to belong to the Östermalm area, please do not picture in your mind any resemblance of the super centric and fancy features that are often associated with Östermalm; instead, Fredrik's apartment is in a quiet, suburban-like neighbourhood in the northeastern part of Östermalm, 25 min by foot of the city center.
On a more postive note, the apartment was clean, nicely decorated and less than 5 mins away from a metro station.
