I stayed at this hotel for 2 nights in mid November and found my stay "fine" overall, I had booked a compact double room for myself and my partner during our short weekend getaway trip.
The positives were the price was quite reasonable, the location was very convenient especially if you are getting the train from Arlanda Airport as the hotel is directly above the platforms.
Negatives were that the room was very worn to a point of the walls being very dirty from past uses, the furniture being overly worn and not being updated in a while and the bed was on the more uncomfortable side with the feeling of springs through the mattress.Initially you are only given 2 pillows, which for 2 people is quite poor given I had booked for 2 people, however, I had requested more at the reception which they did provide so not a real issue.
If you are looking for convenience for a short weekend stay, I would say this hotel will do the job as it is well situated to explore the main regions of Stockholm such as the shopping district and plenty of food choices around. If you are looking for a more comfortable stay with a bit more class and spacious room, I would recommend exploring other hotels though.
