Is Ullern a good area to stay in Oslo?

Ullern is the coastal strip west of Frogner: Skøyen at the bottom, then Bestum, Montebello and the Ullernåsen ridge climbing away from the fjord, out to the Lysaker river and the Bærum boundary. Skøyen is one of Oslo's biggest office districts and has the business hotels to match, which is the only reason a visitor ever ends up here.

On a map it looks like a bargain: it is west, it is on the water, it is two stops past Frogner. In practice the borough is a commute. Karl Johans gate is roughly five kilometres away, the streets between the stations are detached houses and company car parks, and after six in the evening Skøyen empties completely - there is no restaurant strip and no reason to walk anywhere.

There is one honest case for it, and it is narrow. Skøyen station is on the Drammen line, so the airport express and every western local train stop there, and a room here can be a third off a Frogner rate. If you are in Oslo to work at Lysaker or Skøyen, book it. If you are here for the city, you are paying in transfers for a district with nothing at street level.
