Good balance price - quality. Location was excellent in the center of Gamla Stan, so close to everything (T-banna is 3mins walking). The apartment was very clean. There is a supermaket (Coop Nära) at 5min walking distance. It has everything needed for a good stay.
It is worth to mention that even though the ad says 5 people, it is really 2 normal beds and some added mattresses for the other 3, which makes the other 3 beds uncomfortable for adults or grownup children (can be ok for small kids).
This apartment also has a self-cleaning policy which means you are supposed to do some cleaning of the apartment before leaving or pay additionally for the cleaning. The apartment is small and easy to clean fast so we did the self cleaning ourselves and was not a big issue
