This is an interesting building, worth looking around. As most people have said it is not a place made for a long visit but I think it makes for a nice combination with a walk around the myriad of small streets in the old town.
The presence of the temporary exhibition was a real plus.
As one other writer mentions go into the upside down house which is just beside the hospice (and free) while it is still there. It is a truly strange sensation trying to stand upright!
