Nice, clean, and well accommodating flat in Gamla Stan. The location is unbeatable! We were able to walk everywhere and enjoyed the old town charm. We had difficulty with the lock to the front door, but we were fine once we figured that out. As others have mentioned, it is rather loud in the mornings but the noise encouraged us to get out of bed and start our day.
All in all, it was a good experience and I would probably stay there again.
