We really loved our stay at Ana's place. The whole house is spectacular, a truly Norwegian Romantic house. The interiors are delightful and the place is cosy and really welcoming. Ana is really willing to help in every way possible and we found in her a reliable host. Although you need to walk to get the bus or the subway, the walking distance is no more than 5-10 minutes and the views are really nice. I definitely recommend Ana's place if you are planning on visiting Oslo. You will not regret it.
