The host was rude and dismissive. He was obviously (stated outright) in a hurry, and kept cutting me off when I had questions. His overview of the room and information about what was in the room was cursory - he waved a hand toward the open door "it's in there", and "you'll figure it out" were standard responses.
If you stay here, please note that there is public transport from the National Theatre train station to the location, even though there are two busses that go there within two blocks), which when it's 12c/54f and raining and I'm lugging two suitcases would have been helpful to know ahead of time. The fact that only the walking option was given stands out the most as all of my other hosts have been so thoughtful ahead of time with their communications and suggestions.
As the room is *tiny* (barely enough room to open one suitcase without putting it on the white comforter, and you have to close the door to do even that), even a little information on the area (and an updated pamphlet on Oslo -the on in the room was old) and a warm welcome would have gone a long way. There is a single serving nespresso coffee maker and a hot water kettle and a tiny dorm fridge crammed in at the foot of the bed - and that's all the access you get to anything. The shared bathroom is fine, with an admittedly welcome heated floor even in the summer.
The location is certainly at the hub of the harbor area, in the expensive shop/restaurant part of town. The roof terrace has an ok view of the harbor - but isn't anything special. Whoever was up there the night before left fast food trash everywhere - or that could have been the seagulls, I suppose. Easy walking distance to the Fortress/Castle (must do) and access to the ferries / fjord cruises leaving from the docks. The host suggests Starbucks for breakfast . . cheap and quick and open, but hardly local fare. FYI, know that the locker storage at the Central Station is your best bet for keeping luggage, especially with the 10am mandatory checkout in the morning. Plus there are restaurants and coffee shops at the station that are open and tasty for breakfast. I'd say this is fine for one night to crash if you want to be on the docks, but wow, I wouldn't want to stay here again, or for any longer than I had to.
