We had an amazing long weekend in Oslo staying at Mari & David's. We were travelling with our toddler and their place is well equipped with everything we need including toys, toddler beds, toddler cutlery and pram. Its less than 10 minutes walk to the centre. There's a small shop next to it for basic necessities and 2 more bigger groceries if you'd like to stay in and make food. The house is lovely and we'd highly recommend it to anyone visiting Oslo.
