The flat has plenty of rooms. If u stay in one of the rooms it is great. We travelled with the big geoup and i got to sleep on the sofa in the livingroom, so it god a bit loud there and i also felt very cold, since the cold came through the window.
But the flat is great, has got 2 bathrooms, ideal for a group trip! Close to centralnstation, amd just 3 stops from the dome.
