Before our arrival the hostel was very flexible and answered all of my questions. The apartment is a nice size. It can be a little noisier since it's part of a hostel, but when you keep the window closed, it won't bother you. The atmosphere of the hostel is really nice, and the breakfast you can buy was great. Location is amazing, within 5-10 minutes (walking) you're in the busiest shoppingstreets of Stockholm. Lastly, as the other reviews said, the sauna and laundry room aren't part of the apartment, but don't let that deter you from renting this space. Me and my colleagues loved our stay here.
