The apartment is really close to the city centre - ten minutes walk from the Cathedral. It is clean and comfortable. We especially liked the seating area which was comfortable for five of us to watch TV and chat. The host was extremely helpful with restaurant recommendations, replying to emails very quickly with fantastic ideas - so much so that we ended up going to every restaurant she recommended and they were all fabulous! It was very quiet and we didn't hear any noise from neighbours. Check-in was easy and efficient. The supermarket downstairs has a small selection of food - fine for basics like coffee, tea, milk, juice etc. The rooms are quite small but perfectly comfortable and included plenty of clothes hangers and so on. The shower was hot and powerful. Didn't encounter any problems whatsoever and would stay here again if we came back to Oslo. Thanks!
