Where to sleep in Oslo — the neighborhoods and the picks, siesta side to fiesta side.
Sentrum & Aker Brygge — waterfront
Fjord promenade, restaurants and every tram line.
Grünerløkka — the fun barrio
Vintage shops, coffee and the river walk; Oslo's most alive streets.
Frogner — elegant and quiet
Embassy streets by Vigeland Park.
Hostel note
Oslo's hostels and 'hotel-lite' chains (Citybox) are the honest hack in an expensive city.
