I think it feels at once calm and hectic, removed and immersed. The entire situation is set up as this duality - so, for example, the tasteful interior of the apartment offers a haven for the threatening hostility of the city, but no protection. You visit the apartment every week, while the owner is out. You get a short list of housekeeping tasks to do. But there are also other activities that are not on the list. And you're entirely free to choose what you do. There's no victory or failure conditions in Sunset, but everything you do nudges the narrative a little bit.
