We've had a great time in Oslo, also because of Anders and his flat.
It's located directly in the area of Tjuvholmen next to the haven close to some bars, coffeeshops & restaurants.
The apartment was clean and provided everything you'll need for a trip to Oslo.
Anders himself was very nice and welcoming to us.
On the weekend the area itself is surrounded by people, kinda crowded and sometimes someone will be loud on the street. But still that's okay and can happend everywhere in the world.
The only thing that was kinda weird (and has nothing to do with my critique of Anders or the apartment, but still I have to mention this) that the office building right on the opposite of the street was having it's lights on even in the night where NOONE is working there.
I hope the company will LEARN to switch off the light, otherwise it would be some random waste of energy. :)
To sum it up for you:
The appartment as well as Anders - your host - are great! Thank you
