Tiny indeed but good for light travelers or low-budgeted. The location is the main advantage, I'd say. Smack in the center of the busy historical area.
There's natural light coming through the rooftop window at all hours of the day, but no view of course. Not an issue, really. Just go to the nearest cafe or restaurant and enjoy the view from there.
Try to be quiet and mindful because there's no autistic isolation between the stairway and the rooms along it.
