Pros - location is ideal. Middle of Gamla Stan, so you’re equidistant to all parts of the city. The apartment gets great light and it’s pretty quiet given the area.
Cons - it’s 5th floor walk up, so I wouldn’t recommend to anyone who can’t do stairs. The bathroom is tiny and the shower will soak the bathroom floor. It’s a little hard to find as well.
There are 2 twin beds, which is useful for if your spouse is driving you crazy, but not as good if you’re looking to cuddle.
