This small apartment is perfect for a couple. Me and my girlfriend traveled to Stockholm for a week but since we are student we didn't have much budget to afford fancy hotels or other locations in the city. But fortunately we found this relatively inexpensive (Stockholm is very very pricy) and it was perfect because it provided all we needed. Matter of fact the place had a super nice bed, a table for 2 and a small kitchen that was more than sufficient to cook a couple of meals (we saved a lot of money on the dinners and breakfasts thanks to it).
The place was clean, it's not super near the center (about 25 min walking) but it's 5 min to the nearest subway (I suggest you pay for a 72 hours or more ticket for it since it costs 45 kr per ride).
Definitely would recommend this place if you are in two travelling together!
