Overall a very good experience. The location is outstanding, just a few minutes walk to the old town in on direction and in the other direction just a few minutes walk to Medborgarplatsen (great place to drink beer at in the summer times!). The apartment has everything u need for cooking and is clean and have a nice terrace.
On the down side - Bed is not very comfortable and quite noisy as soon as you moving, but we were aware of that it was a sofa bed, and those are never like a real bed of course so it was fine.
We would also have appreciated if we could have been able to use the laundry room (that all apartment buildings in Sweden have) but we were not allowed to do that for the owners.
