We came as a family of four with children. Seems like all is the family rooms are on the first floor. The rooms have bunk beds adjacent to the king size bed so if a little one once to jump in bed too, you all will fit. The room is small, but we’re in downtown Stockholm. It’s a great location next to the ferry and metro. You can take stairs up nearby to get to the main commercial area with restaurants and bars.
For me, I wish there was a coffee shop closer by, but there are plenty of bakeries (Bayeri) within a 10 minute walk.
