Just one night before arrival we booked at Jang's and Christian's place. They were really quick to reply on our questions and our booking. Christian is very enthousiastic about explaining everything you need to know for your stay. Room was not to big but very clean with free coffee and tea. Bed slept awesome. I recomment the rooftop for a nice quiet afternoon.
The place is right in the middle of hip and happening, in the harbour of Oslo. Just a short walk from downtown and the ferry's. I would stay here again next time. Price is very reasonable for the whole thing.
Thanks Yang and Christian for everything.
