Chad's two-bedroom souterrain flat is an excellent place to stay in Oslo. It's surprisingly roomy, very modern and in great condition and clean. The open kitchen has an oven, a microwave, a stove, a fridge and a dishwasher, so it's easy to prepare meals. There is a dining table (though we used the bar stools in the kitchen) and a comfortable couch with a big TV. The two double beds are very clean and good size. The metro and supermarkets are within walking distance.
Chad was very friendly and helpful and we felt at home immediately. Highly recommended!
