Highly recommend the Sommerro Hotel in Oslo. Well located and it’s a 4 min walk from the nearest metro. I paid 250 usd for a standard room and I got a 2 level upgrade to a deluxe room. As part of the Amex benefits, early check in, late checkout and 150 usd credit was provided. The rooms are very comfy and the lighting and technology provided in the room just works beautifully. If you like to workout, they have a fully fitted commercial gym, an infrared sauna with a cold plunge pool at the spa and also an outdoor rooftop heated pool and regular sauna at the rooftop. The breakfast buffet is extremely tasty and fresh and all the meals I had at the in house restaurant is amazing. It’s really one of the best hotel stays I ever had.
