The place had perfect location for our purposes. To central it took about 30 minutes and it was easy to reach from Bromma Airport. There was supermarkets and few great pubs in walking distance.
Both the bed and the sofa bed were comfortable. Fit four adults perfectly, there's no privacy, since it's a studio, but that's what we paid for.
All in all great stay, expect that the floors were a bit sticky and there was a lot of dust under the sofa bed, but we spent so little time in the apartment so it was not such a big problem. Apart from those, the apartment was clean.
