The Apartment was exactly as pictured.
By Oslo standards, its much roomier vs what you find more centrally which is ideal if you need a bit more space (family & children). It's also in a quiet residential area with nice restaurants and museums nearby.
Communication with host was quick and easy. Checking in was also fairly straight-forward.
Oslo can get quite hot in the summer (25C - 30C) (most appts do not have A/C), so you do have to close the blinds during the day to keep the place cooler (otherwise it can get very hot inside).
My family had a very pleasant stay and we are happy to recommend the appt to other travellers.
