Nice report ... ! I've visited Stockholm several weeks ago (for a few days) with my car and it is indeed a pleasant city where virtually everyone speaks English. I did however make the unforgivable mistake of entering the old city (Gamla Stan) with my car. It was a hellride filled with traffic jams and confusion until I found a way to escape after two hours.
Despite that, I'm eager to visit the city again in the near future ... !
I feel your pain, I made the mistake of taking a taxi a few times in/out of Gamla Stan!
