The location is perfect - 10 minutes of slow walk from the central station, about the same to the main tourist attractions on Karl Johans street. Street with a lot of good bars is just one block away from the apartment (try Crowbar and Café Sara, both are pretty good and inexpensive by Oslo standards). Trendy Grunerlokka district with lots of bars/cafes is just 5 minutes away. The apartment is pretty quiet, and the bedroom has a window facing the inner yard, so I had a good night sleep. The apartment looks better than on pictures (which are of low quality). It is pretty spacious, clean, and has all the amenities you need, including the washing machine, dishwasher, fridge and separate freezer, oven etc. The host is very nice and attentive. Basically, the only issue I had was with the bathroom and the towels (cleanliness could definitely be improved). Except that, everything was perfect.
