I have had the most amazing time in Oslo thank you to my great host OP.
I have no words to describe the amazing, friendly, charismatic, genuine guy, and awesome host that he is.
Also his apartment is really close to the city centre and therefore near every touristic venue you could think of.
I was able to walk everywhere and during my stay didn't use the public transport at all.
The apartment is also very comfortable, very clean and very peaceful.
I recommend OP's place without hesitation.
If you ever in Oslo this is the place to stay!
