The Apartement had enough space for the three of us. The kitchen was well equipped (but no salt, coffee, etc.). There was a problem with the shower as the water was running out beneath the shower door and the ventilation is a little noisy at night but you get used to it. The TV turned off on its own after some minutes.
Otherwise it's nice staying there.
The location is not the best, as the center is about 2-4km away. But there is a city railwail around the corner. With one change you are in the city centre in about 15-20min. There is also the chance to rent a scooter. They are super fun, you are very flexible, as you can go nearly everywhere around stockholm and the dayticket is pretty cheap (about 10$).
