The large hotel between Potsdamer Platz and lovely Gleisdreieck Park straddles the handy U2 metro line. Inside, it's all about eco-friendly Scandinavian design; every floor has a season theme that determines the look of the halls and the furniture in the comfy rooms. No single-serving packaging in the breakfast room; the honey is even produced in the bee hives on the roof. The staff treats guests in a fresh, informal way, and the hotel is perfect for disabled travellers, and children. Free wifi.
