I enjoyed my stay at this quaint little apartment. It is in the middle of a historic area so it is extremely walkable as well as easy to catch a taxi. It can be a little loud at night especially if you sleep with the windows open - no one in Stockholm has air conditioning.
As for the apartment it is pretty small - It is one big bedroom that serves as living / sleeping, as well as a compact kitchen. I think the apt could use some reworking to maximize space and functionality for guests but it worked for 1-2 people, especially if you are planning to be out in the town most of your trip.
Overall, I had a good experience and the host was very communicative. Thank you Frederick!
