This hotel is a great deal. I stayed for one night and managed to get a room for under 400kr (£29). The room I booked didn’t have an external window (as expected), but there was natural light, coming through the atrium. It was very clean, small but well designed, and had the amenities you would expect. There is a gym in the atrium area, which could be noisy, but it’s closed at night. Buffet breakfast was included and I thought it was very good. Included an assortment of hot food (eggs, beans, bacon, sausages), cereals, yogurts, fruit, bread, smoothies and ginger shots (!), coffee, tea, and a fridge of alternative milks for vegans or the lactose intolerant. Only issue is that there aren’t enough tables - on the weekend everyone seemed to come down between 9-10am. Would recommend if you need to be in Kista, or you don’t mind the commute into Stockholm.
