Fredrik’s apartment is very well located. Wherever we check on the map was max. 5-10 mins away by foot (both sightseen and restaurants/ bars/ night outs. We almost never needed to use transportation. The apartment has almost everything so you wouldn’t need anything. Even though if you need, I am sure Fredrik or his neighbor William will do their best to provide as Fredrik already did to me. I stayed at his apartment in the coldest season of Oslo but the heating of the house was very good so we didn’t face any problem about it too. Whenever we needed an answer William responded us immediately so the communication wouldn’t be better.
Last but not least, I’m sure that I will stay at his house if I visit Oslo again. I highly recommend his apartment for couples and very small group of friends.
