Pros:
Excellent location in happening Gamla Stan. Walk to everywhere that matters.
Clean, quiet apartment.
Cons:
No flexibility on checkout time or even leaving bags . This means you have to hike to central station to stow your bags if you plan to stay in the city past checkout time
Communication response time was not great. Copy paste answers.
Front street door does not lock.
Overly modern gimmicky accessories like a door lock that whirs for 15 seconds before it locks and a toilet that has controls like a smartphone.
Transportation recommendations are incorrect. Taxi and Uber are way more expensive than stated, and Arlanda express is cheaper than stated, particularly for 2 or more people.
Everything is tiny to the point of being inconvenient
