Cute quirky apartment! It feels like a reclaimed warehouse (probably because it is a reclaimed warehouse), so it's set up a bit differently from a typical apartment. The downstairs has a small kitchen and large living room with an enormous wall-to-wall glass window. This gives you a view of the train tracks, the harbor beyond, and the mountains beyond that. Just beautiful. At the time I was there (March), there was a pair of nesting bald eagles quite close as well, and Patrick had even left a pair of binoculars to see them better.
The bed (which is comfortable) takes up most of the upper loft, so that's really just a sleeping area (with a fantastic view when you wake up). One thing I appreciated about the downstairs was multiple electrical outlets in various places. There's a TV with a guest Netflix account and an electric fireplace. Also a working pinball machine, that I thought I had no interest in, but was actually pretty fun. :)
There is some noise from passing freight trains (although it was quieter on the weekend--coincidence? I don't know), including at night, so if you're a light sleeper, take a pair of ear plugs. Didn't bother me, though. Because you're on the 4th floor, I don't think anyone from the street level could see into the apartment, at least not if you stood a bit back from the window, but there are also shades for when you want guaranteed privacy. But during the day it was a lovely place to sit and work.
There are multiple stores, markets, restaurants, and bars within easy walking distance, and public transportation is right there too. It was also a very walkable neighborhood for exercise. You would not need a car to stay here.
