This is some pictures, on the way to the school, the location is in the city.
You can see a little guide on the map when you go get of the tran, and the stations stop is "Domkyrkan"

But it´s a little bit tricky to find the school when they  don´t have any offical sign.

The buildning is yellow with a nice and elegant entrance, the doors are always  locked so you need to ring the dorbell.
