Thanks for providing the link to this Oldie but Goodie.
Agree with the comments about Stockholm's charm and glad we could experience Old Town. Lucky for us we unexpectedly chanced upon a courtyard performance by the Royal Marching Band at the Royal Palace.
As to the Clarion Post Hotel until reading this thread I did not even know there were rooms in the old Post Office part of the hotel that includes the reception area and restaurant. We lucked out in the glass tower with fun views of the trams and busses below as well as a super sunset.
